Answer:
0.2 is the correct answer.
Answer:
-8.3 + 9.2 - 4.4 + 3.7
= -8.3 + 9.2 + (-4.4) + 3.7 {Additive inverse}
= -8.3 + (-4.4) + 9.2 + 3.7 {Commutative Property}
= [ -8.3 + (-4.4] + [ 9.2 + 3.7] {Associative property}
= - 12.7 + 12.9
= 0.2
answer is 0.2
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.

Aaron can join a gym that charges $19.99 per month, plus an annual $12.80 fee, or he can pay $21.59 per month. He thinks the secound option is better because he plans to use the gym for 10 months. Is Aaron correct.
Answer:
the second gym is more expensive
Step-by-step explanation:
i got it right when i did the test/quiz
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.

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
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
B. 19.1cm

A 5-pack of ice cream bars costs $2.15. What is
the unit price? ( Make sure to put your answer in terms of dollars and cents)
Answer
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

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

You may ask how got these numbers. Well there is a pattern (x+4). X is the previous number.
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
