A group of friends are going to see the newest action movie. The price of a ticket is $6.25. As a group, they spent $12 on refreshments. If they spent a total of $30.75 on tickets and refreshments, how many people went to the movies?
Which equation represents the scenario?
How many people went to the movies?
Answer:
3 people went to the movies. Equation: $6.25p+12=30.75
Step-by-step explanation:
To find your answer, subtract $12 immediately because it is one cost and not unknown. Then, divide the difference between $30.75 and $12 ($18.75) by $6.75. The quotient is the number of people went to see the movie. In the equation, solve for p.

Answer this math question to earn an extra 100 participation points for this week: Mr. Tuneze, Ms. Janette, and Mr. Afton went to a restaurant and the total for all their dinner was $25. Each of them gave the server a $10 dollar bill. Their change was $5 but the server could not think of how to split $5 evenly between three people, so he gave each one of them $1 and kept $2 as a tip. Here is the problem: After receiving a dollar back, each person had paid $9 for dinner for a total of 3 times $9 equals $27. Add the $2 kept by the server, the total is now $29. What happened to the remaining dollar?
Answer:
Trick question ;)
Step-by-step explanation:
The misdirection in this riddle is in the second half of the description, where unrelated amounts are added together and the listener assumes those amounts should add up to 30, and is then surprised when they do not — there is, in fact, no reason why the (10 − 1) × 3 + 2 = 29 sum should add up to 30.
The exact sum mentioned in the riddle is computed as:
SUM = $9 (payment by Guest 1) +
$9 (payment by Guest 2) +
$9 (payment by Guest 3) +
$2 (money in bellhop's pocket)
The trick here is to realize that this is not a sum of the money that the three people paid originally, as that would need to include the money the clerk has ($25). This is instead a sum of a smaller amount the people could have paid ($9 × 3 people = $27), added with the additional money that the clerk would not have needed had they paid that smaller amount ($27 paid - $25 actual cost = $2). Another way to say this is, the $27 already includes the bellhop's tip. To add the $2 to the $27 would be to double-count it. So, the three guests' cost of the room, including the bellhop's tip, is $27. Each of the 3 guests has $1 in his pocket, totalling $3. When added to the $27 revised cost of the room (including tip to the bellhop), the total is $30.
To obtain a sum that totals to the original $30, every dollar must be accounted for, regardless of its location.
Thus, the sensible sum that we really desire is this one:
$30 = $1 (inside Guest pocket) +
$1 (inside Guest pocket) +
$1 (inside Guest pocket) +
$2 (inside bellhop's pocket) +
$25 (hotel cash register)
This sum does indeed come out to $30.
To further illustrate why the riddle's sum does not relate to the actual sum, we can alter the riddle so that the discount on the room is extremely large. Consider the riddle in this form:
Three people check into a hotel room. The clerk says the bill is $30, so each guest pays $10. Later the clerk realizes the bill should only be $10. To rectify this, he gives the bellhop $20 to return to the guests. On the way to the room, the bellhop realizes that he cannot divide the money equally. As the guests didn't know the total of the revised bill, the bellhop decides to just give each guest $6 and keep $2 as a tip for himself. Each guest got $6 back: so now each guest only paid $4; bringing the total paid to $12. The bellhop has $2. And $12 + $2 = $14 so, if the guests originally handed over $30, what happened to the remaining $16?
Now it is more obvious that the question is quite unreasonable. One cannot simply add a couple of payments together and expect them to total an original amount of circulated cash.
More economically, money is accounted by summing together all paid amounts (liabilities) with all money in one's possession (assets). That abstract formula holds regardless of the relative perspectives of the actors in this exchange.
The guests of the hotel paid $27, but also have $3 among their pockets at the story's end. Their assets are $3, and their liabilities are $27 ($30 = 27 + 3). Thus, the original total is accounted.
From the perspective of the hotel clerk, the hotel has $25 in assets and lost $5 in liabilities ($30 = 25 + 5).
From the perspective of the bellhop, his assets are $2, and his liabilities are $3 to guests and $25 to the register at the desk ($30 = 2 + 3 + 25).
To illustrate the issue through equations:
1) 10 + 10 + 10 = 30
2) 10 + 10 + 10 = 25 + 2 + 3
3) 10 + 10 + 10 - 3 = 25 + 2 + 3 - 3 (adding -3 to both sides of the equation to cancel out the +3 on the right side)
4) 10 - 1 + 10 - 1 + 10 - 1 = 25 + 2
5) 9 + 9 + 9 = 25 + 2 (obs: tip to bellhop has already been paid)
6) 27 = 27
How the riddle is deceptive comes in line 8:
7) 9 + 9 + 9 = 25 + 2
8) 9 + 9 + 9 + 2 = 25 (pushing +2 to the other side without inverting the sign)
9) 27 + 2 = 25
10) 29 != 25
How it should be:
7) 9 + 9 + 9 = 25 + 2
8) 9 + 9 + 9 -2 = 25 + 2 -2 (adding -2 to both sides of the equation to cancel the +2 on the right side, which means the bellhop returned the tip or gave a discount of $2)
9) 9 + 9 + 9 - 2 = 25
10) 27 - 2 = 25
11) 25 = 25
The puzzle should subtract the bellhop's tip from the $27 rather than add it.
3x-1-8=41+x+5 solve for x!
Answer:
[tex]x=55/2=27.5[/tex]
Step-by-step explanation:
We have the equation:
[tex]3x-1-8=41+x+5[/tex]
First, let's simplify our equation. Subtract on the left:
[tex]3x-9=41+x+5[/tex]
And add on the right:
[tex]3x-9=46+x[/tex]
Now, add 9 to both sides:
[tex]3x=55+x[/tex]
Subtract x from both sides:
[tex]2x=55[/tex]
Divide both sides by 2. So, the value of x is:
[tex]x=55/2=27.5[/tex]
And we're done!
Answer:
x = 27.5
Step-by-step explanation:
3x - 1 - 8 = 41 + x + 5
~Combine like terms
3x - 9 = 46 + x
~Add 9 to both sides
3x = 55 + x
~Subtract x to both sides
2x = 55
~Divide 2 to both sides
x = 27.5

This Question is Incomplete
Complete Question
Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of $65 along with an
hourly rate of $28. The plumber only charges for a whole number of hours. Anand would like to spend no more than $250, and he wonders how many hours of work he can afford.
Let H represent the whole number of hours that the plumber works.
1) Which inequality describes this scenario?
Choose 1 answer:
A. 28 + 65H < 250
B. 28 + 65H > 250
C. 65 + 28H < 250
D. 65 +28H > 250
2) What is the largest whole number of hours that Anand can afford?
Answer:
1) C. 65 + 28H < 250
2) 6 hours
Step-by-step explanation:
We are told in the question that:
Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of $65 along with an
hourly rate of $28. The plumber only charges for a whole number of hours.
Hences we have:
$65 + 28 × H
We are told that:
Anand would like to spend no more than $250,
Hence,our equation becomes:
$65 + 28H ≤ $250
Where H = Hourly rates of the plumber.
1) Which inequality describes this scenario?
From the given options and our calculations above, Option C) 65 + 28H < 250 is the correct answer
2) What is the largest whole number of hours that Anand can afford?
We would use our equation above to solve for this.
65 + 28H < 250
= 65 + 28H ≤ 250
We convert or inequality sign to equal to sign
= 65 + 28H = 250
28H = 250 - 65
28H = 185
H = 185/28
H = 6.6071428571 hours
Therefore, the largest whole number of hours that Anand can afford is 6 hours
Answer:
65+28H [tex]\leq[/tex] 250
6 hours

PLEASE ANSWER WILL GIVE BRAINLIEST!!!!!! m and n are positive integers greater than 1. The product of GCD and LCM of the integers is 143. Find m + n.
Answer:
We see that it is always possible to write both M and N as the products of the same prime factors, albeit with different exponents. Some of the exponents will need to be zero.
Now, both GCD(M, N) and LCM(M, N) are products of the same prime factors where the exponents in G are the least of the corresponding two, whilst in L they are the largest:
GCD(M, N) = p min(a, α) q min(b, β)· ... · r min(c, γ),
LCM(M, N) = p max(a, α) q max(b, β)· ... · r max(c, γ).
Now, (2) thus insures that (1) holds. To continue the example:
GCD(12, 10) = 213050 = 2,
LCM(12, 10) = 223151 = 60.
Naturally, 12×10 = 2×60.
Step-by-step explanation:
The value of m + n if, m and n are positive integers greater than 1. The product of GCD and LCM of the integers is 143 is 24.
What is the product?In mathematics, a number that is obtained by multiplying two or more other numbers together is known as the product. For instance, the result of multiplying 2 and 5 together is 10, or the product.
Given:
m and n are positive integers greater than 1,
The product of GCD and LCM of the integers is 143,
The product of GCD and LCM of the integers is equal to the number's product, so,
m × n = 143
Factorize the number 143 as 11 × 13
As you can see that there are only two numbers whose product is 143, and they are greater than 1,
Thus, m = 11 and n = 13.
m + n = 11 + 13 = 24

Jamel is selling a gold watch that he bought 5 years ago. He paid $375 when he got the watch, however he is going to sell it for 25% more than what he original bought it for. What is the total cost he is selling it for.
Answer:
Step-by-step explanation:
Buying price = 375
Mark up = 25%
Mark up value = (25/100) * 375 = 93.75
Selling Price = buying price + markup value
Selling Price = 375 + 93.75
Selling Prince = 468.75
A quicker way (perhaps) is
Selling price = buying price (1 + 0.25)
Selling prince = 375*1.25 = 468.75

Aaron is incorrect. Because the cost of the second option is higher than the first one.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Aaron can join a gym that charges $19.99 per month, plus an annual $12.80 fee. Then the total cost for 10 months will be
⇒ $19.99 x 10 + $12.80
⇒ $212.7
If he can pay $21.59 per month. Then the total cost for 10 months will be
⇒ $21.59 x 10
⇒ $215.9
He thinks the second option is better because he plans to use the gym for 10 months. Aaron is incorrect. Because the cost of the second option is higher than the first one.

The perimeter of a square is 54cm. Find the length of a diagonal, rounding
to the nearest tenth.
A. 182.3cm
B. 19.1cm
C. 13.5cm
D. 22.4cm
Answer:
B. 19.1cm
Step-by-step explanation:
Perimeter of a square = 4 × length
Perimeter = 54cm
Perimeter of a square = 4 × length
54 = 4 × length
54 = 4l
Divide both sides by 4
l = 54 / 4
= 13.5cm
Find the length of a diagonal,
Diagonal = hypotenuse
Using Pythagoras theorem
Hypotenuse^2 = opposite^2 + adjacent^2
Opposite = adjacent in a square because of the equal length
Opposite = adjacent = 13.5cm
Hypotenuse^2 = opposite^2 + adjacent^2
= 13.5^2 + 13.5^2
= 182.25 + 182.25
Hypotenuse^2 = 364.5
Find the square root of both sides
√Hypotenuse^2 = √ 364.5
Hypotenuse = 19.09cm
To the nearest tenth = 19.1cm
