A. $32 + $45 + $39 : 3

O C.3 × $32 + $45 + $39
D. ($32 + $45 + $39) = 3
Mark for review (Will be highlighted on the review page)
Next Question >>
Answer:
I would have to say A) 32 + 45 + 39: 3
Step-by-step explanation:
This is because when finding the average of literally anything, you want to add up all the numbers, and then divide the sum of it by the numbers you added up.
for instance: 32 + 45 + 39 = 116. now, we need to divide by 3 because we added 3 numbers up.
116 divided by 3 = x
x is our average cost per books.

If 7x + 5y = 25 and 3x + 2y = 10, what is the value of x +y?
Answer:
Step-by-step explanation:
7x+5y=25
3x+2y=10
21x+15y=75
21x+6y=30
0x+11y=45
11y=45
y=45/11
y = 4.09
sub in 4.09 into equation 1
7x+5(4.09)=25
7x+20.45=25
7x=25-20.45

A children's birthday party at an indoor play center costs $50 to rent the space and $6.25 per child. Gina wants to spend no more than $100 on her son's fourth birthday party. Write an inequality for the number of children who can attend the birthday party, and solve the inequality.
A) 50 + 6.25x 100; x>8
B) 50 + 6.25x 100; x 8
D) 50 + 6.25x 100; x<8
Answer:
D

The slope of the given line is 4.
What is slope?The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Given that, a line passing through points (3, 9) and (1, 1) we need to find the slope of the line,
Slope = y₂ - y₁ / x₂ - x₁
So,
Slope = 9-1 / 3-1 = 8/2 = 4
Hence, the slope of the given line is 4.

It cost Randy $515.20 for new carpet in his bedroom. If the room is 11.5 feet wide by 14 feet long, what was the cost per square foot?
Answer:
$3.20
Step-by-step explanation:
First, find the area in square feet of his room:
Use the area formula, A = lw, where l is length and w is width:
A = lw
A = 14(11.5)
A = 161
So, his room is 161 square feet.
To find the cost per square foot, divide 515.20 by 161:
515.20/161
= 3.2
So, the cost per square foot was $3.20

What is the solution to the equation 23(y−6)=−(y+2)+1 2 3 ( y - 6 ) = - ( y + 2 ) + 1 ?
Answer:
Substitute the given value into the function and evaluate.
23 (y − 6) = −(y + 2) + 1 = y = 137/24
2 = y = 137/24
3 = y = 137/24
y − 6 = −(y + 2) + 1 = y = 5/2

Answer:
The numerator is 3, so the whole thing would say 3/11=12/44
Step-by-step explanation:
divide the second fraction down as much as possible, and you will get 3/11.
12 divided by 4 equals 3
44 divided by 4 equals 11
so 3 is the numerator and 11 is the denominator
Answer:
3
Step-by-step explanation:
lets make teh blank x
x/11 = 12/44
x/11 = 3/11
x = 3

three-fourths of a number is at least -18
Answer:
3/4*X < -18
( put a line underneath the less than sign ) ( Astric's means multiplication )
Step-by-step explanation:
Hope this helped, Have a Wonderful Day!!
Answer:
x ≥ - 24
Step-by-step explanation:
Let's solve this with an equal sign and then decide how to handle the at least part.
3/4 x = -18 Multiply by 4
3/4 * 4 x = -18*4 Cancel the left, multiply the right.
3x = -72 Divide by 3
x ≥ -24
You need the greater than to indicate that 3/4 of a number can give something larger than - 18.
You need the equal sign to fulfill at least.
At least, in this question means "get larger."
so x > - 24
