Answer:
x = 5
Step-by-step explanation:
Here, we are interested in calculating the value of x.
We can obtain this from the given angle in the question.
Mathematically;
<CDE = <YDE + <CDY
Thus;
147 = 10x-3 + 21x-5
147 = 31x -8
31x = 8 + 147
31x = 155
x = 155/31
x = 5

1C. When you review your monthly checking account statement, which
statement below would indicate that you deposited more money than you
spent?
Your previous balance is higher than your ending balance
Your fees are greater than your starting balance
O Your withdrawals are larger than your fees
Your ending balance is higher than your previous balance
Answer:
Your ending balance is higher than your previous balance
Step-by-step explanation:
An account statement is prepared periodically or on request by banks for the consumption of their customers.
This is a record of income and withdrawals on that account.
If at the end of a given period of time, the ending balance of the period is greater than the previous balance, then the account holder has deposited more money than he/she spent. Hence the answer.
You want to make bouquets of balloons. You choose 15 and 12 balloons. Every bouquet will have the same number of each color. What is the greatest possible number of bouquets you can make using all the balloons? Estimate how much you will earn if you sell each bouquet for $3.99.
Answer:
3 ; $11.97
Step-by-step explanation:
Given that:
Balloon options : 15 and 12
Every bouquet has same number of each color :
Greatest possible number of bouquet possible using all the balloons :
Greatest common factor of both 15 and 12:
15 : 1, 3, 5, 15
12 : 1, 2, 3, 4, 6, 12
Hence the greatest common factor of both 15 and 12 is 3
Hence,
Greatest possible number of bouquet possible using all the balloons = 3
If each bouquet is sold for $3.99 :
Earning will be :
Number of bouquet * price per bouquet
3 × $3.99
= $11.97

Antonio had $450 in his bank account on Monday. On Tuesday he wrote five checks for $24.50 each. On Wednesday he made three deposits of $45 each. How much money was in his account after the checks and deposits cleared? Explain
Answer:
$462.5 in his account in the end
Answer:
Antonio ends up with $462.50 after the checks and deposits cleared.
Step-by-step explanation:
First make an equation for what we know: Antonio started with $450, he made 5 different checks of $24.50 each, and he deposited $45 3 times.
450 - 5(24.5) + 45 (3)
450 - 122.5 + 135
327.5 + 135
$462.50
Antonio ends up with $462.50 after the checks and deposits cleared.

Step-by-step explanation:
In segment JK, JH = 4x - 15 and HK = 2x +3, where H is between J and K on segment JK.
If JK = 48, find the value of x.
The value of the x in the line segment will be 10.
What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that In segment JK, JH = 4x - 15 and HK = 2x +3, where H is between J and K on segment JK. The value of JK is 48.
For the line segment we can form the expression below:-
JK = JH + HK
JK = 4x - 15 + 2x + 3
JK = 6x - 12
48 = 6x - 12
6x = 48 + 12
6x = 60
x = 60 / 6
x = 10
Therefore, the value of the x in the line segment will be 10.

A family has two cars. During one particular week, the first car consumed 30 gallons of gas and the second consumed 20 gallons of gas. The two cars drove a
combined total of 1050 miles, and the sum of their fuel efficiencies was 45 miles per gallon. What were the fuel efficiencies of each of the cars that week?
Answer:
30 mpg15 mpgStep-by-step explanation:
Let x represent the fuel efficiency of one of the cars. Then 45-x is the fuel efficiency of the other. The total miles driven is then ...
miles = (gallons)×(miles/gallon)
20x +30(45-x) = 1050
-10x +1350 = 1050 . . . simplify
300 = 10x . . . . . . . . . . add 10x-1050
x = 30 . . . . . . . . . . . . . divide by 10
45-x = 45-30 = 15
The car using 20 gallons got 30 miles per gallon; the car using 30 gallons got 15 miles per gallon.
Which of the following functions could be f(x) ?
Answer:
B. f(x) = -x^3 - x^2 + 7x - 4
Step-by-step explanation:
For this problem, we want to find the fastest-growing term in our given expressions and equate them when x is - infinite and when x is infinite to see the given trends.
For each of these equations, we will simply take the terms with the highest power and consider those. The two cases we need to consider is + infinite for x and - infinite for x. Let's check each of these equations.
Note, any value raised to an even power will be positive. Any negative value raised to an odd power will be negative.
[A] - x^4
When x is +∞ --> - (∞)^4 --> f(x) is -∞
When x is -∞ --> - (-∞)^4 --> f(x) is -∞
[B] - x^3
When x is +∞ --> - (∞)^3 --> f(x) is -∞
When x is -∞ --> - (-∞)^3 --> f(x) is ∞
[C] 2x^5
When x is +∞ --> 2(∞)^5 --> f(x) is ∞
When x is -∞ --> 2(-∞)^5 --> f(x) is -∞
[D] x^4
When x is +∞ --> (∞)^4 --> f(x) is ∞
When x is -∞ --> (-∞)^4 --> f(x) is ∞
Notice how only option B, when looking at asymptotic (fastest-growing) values, satisfies the originally given conditions for the relation of x to f(x).

Lupe’s Construction is building a rectangular house that is 16 feet longer than it is wide. They will be putting a 3-foot wide sidewalk all the way around the house. There will be a protective metal strip around the outside edge of the sidewalk. If the house will have a perimeter of 136 feet, how will the four pieces of the protective strip need to be
Answer:
The length of the four pieces of protective strip is 96 feet
Step-by-step explanation:
Let the w be the width of the rectangular house and L is length. Since L = w + 16, its perimeter P = 2(w + L)
= 2(w + w + 16)
= 2(2w + 16)
Since the perimeter of the house P = 136 feet,
136 = 2(2w + 16)
dividing through by 2, we have
136/2 = (2w + 16)
68 = (2w + 16)
collecting like terms, we have
68 - 16 = 2w
52 = 2w
dividing through by 2, we have
w = 52/2
w = 26 feet.
Now, since the side walk is 3 foot wide all around, the width of the house plus sidewalk = w + 3 and the length of the house plus sidewalk = L + 3 = w + 16 + 3 = w + 19.
So, the perimeter of the house plus sidewalk which is the perimeter of the four pieces of protective strip is P' = 2(w + 3 + w + 19)
= 2(w + 22)
= 2(26 + 22)
= 2(48)
= 96 feet
So, the length of the four pieces of protective strip is 96 feet.
∠1 and ∠2 are supplementary angles. If m∠1 = 77°, then m∠2 =
Answer:
m∠2 = 103°
Step-by-step explanation:
Since ∠1 and ∠2 are supplementary angles, together they equal 180. So, you would just subtract 180-77 and get 103. To check if you are correct just add ∠1 and ∠2 ( 77+103) and you'll get 180 :)
If the sum of four consecutive numbers is 1998, what is the third one?
Answer:
[tex]\huge\boxed{500}[/tex]
Step-by-step explanation:
In order to solve this, we have to note that consecutive numbers are numbers that are one more than the last.
If our first number is represented as [tex]n[/tex], then we know that the next number will be [tex]n+1[/tex], the next will be [tex]n+2[/tex], and so on.
Since we want 4 numbers, we can create the equation:[tex]n + (n+1) + (n+2) + (n+3) = 1998[/tex]
Now we want to solve for [tex]n[/tex]. It's important to note that [tex]n[/tex] is our first number.
Combine like terms:
[tex]4n+6=1998[/tex]
Subtract 6 from both sides:
[tex]4n=1992[/tex]
Divide both sides by 4:
[tex]n = 498[/tex]
We want the third number in the set of these four numbers. Looking back to our equation ([tex]n + (n+1) + (n+2) + (n+3) = 1998[/tex]) we can see that the third term here is [tex]n+2[/tex]
[tex]498+2=500[/tex]
