Answer:
x = 30
Step-by-step explanation:
We can begin by subtracting 1/4x from each side so it results like this:
1/2x − 7 = 8
Then, we added 7 to both sides:
1/2x = 15
Lastly, we multiply both sides by 2:
x = 30

Answer:
30 mph
Step-by-step explanation:
let s represent speed and h represent rebound.
Given that s is proportional to h then the equation relating them is
s = kh ← k is the constant of proportion
To find k use the condition s = 20, h = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
s = 2h ← equation of proportionality
When h = 15 , then
s = 2 × 15 = 30 mph
