Let the cost for renting be y and the number of hours be x
then:
y=kx
where:
k is the constant of proportionality
k=y/x
y=$32.5 when x=5 hours
thus;
k=32.5/5
k=6.5
hence the equation is:
y=6.5x
thus the value of y when x=8 hours will be:
y=6.5(8)=$52
Answer:'
<span>A y = $6.5x, y = $52.00</span>
Answer:
x = 3
Step-by-step explanation:
Subtract 5x - 2x to get x on one side. Then your equation will look like like: 2= 3x - 7. Add the 7 to the other side so that you can get the x by itself. 9 = 3x. Then divide by 3
Answer:
13
Step-by-step explanation:
Substitute x for 28 and y for 5:
(28) - 3(5)
28 - 15
13
