Answer:
-15
Step-by-step explanation:
The proportion that could be used to solve for the variable is
; h = 7.5 ⇒ answer b
Step-by-step explanation:
A proportional relationship: one variable is always a constant value times the other, that constant is called the constant of proportionality
- y = k x is the equation of the proportional relationship
- We can write the proportional relationship in the form
The number of walls and the number of hours are increased or decreased together
∴ The number of walls and the number of hours are proportion
∵ 16 walls in 40 hours
∵ 3 walls in h hours
- By using the second rule above
∴
The proportion that could be used to solve for the variable is
Let us solve it to find h
∵
- By using cross multiplication
∴ 16 × h = 3 × 40
∴ 16 h = 120
- Divide both sides by 16
∴ h = 7.5
The value of h is 7.5 hours

We know the perimeter and the length.
The only unknown is the length.
We write the given equation and substitute what we know.
Then we solve for what we are looking for, the length.
Pr = 2L + 2W
288 = 2L + 2(50)
288 = 2L + 100
188 = 2L
94 = L
The length is 94 ft.
Answer: 110.6
Step-by-step explanation: 220 - 109.4 = 110.6
The mid-point of FJ is the number right in the middle of FJ. Find the mean of F & J. Add regardless of sign
4 + 6 = 10
10/2 = 5
Add 5 to -4
5 + -4 = 1
H is your midpoint
True. As long as AB and BC are on the same line, AB + BC = AC
