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

Answer:
I believe it is D.
Step-by-step explanation:
The associative property switches around the order of the digits to make the problem easier. In my opinion it is easiest to multiply the fractions together, and then the whole number.
Answer:
C = 56.5 cm
Step-by-step explanation:
<h3>
The circumference formula is C = πd. If the diameter, d, is 18 cm, then the circumference of this circle is </h3><h3>
</h3><h3>
C = π(18 cm) ≈ 18π cm ≈ 56.5 cm</h3>
The answer is yes, and 108.
