Answer:
Step-by-step explanation:
C = 3.5t....when t = 15
c = 3.5(15)
c = 52.50 <==
The answer is X= 25
You just have to divide 125 by 5
Answer:
x = 5/13
Step-by-step explanation:

Answer:
The expression is equal to 
Step-by-step explanation:
Let
x ----> the number of hours that the roller blades are rented
y ----> the cost of renting roller blades in dollars
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope is equal to

The y-intercept is equal to
----> value of y when the value of x is equal to zero
substitute

For x=h hours
substitute
