Given:

Carmen rents roller skates for $5 plus $2 for every hour she uses them.

To find:

The expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.

Solution:

We have,

Fixed rent = $5

Additional rent = $2 per hour.

Let x be the number of hours.

So, additional rent is $2x.

Now,

Total rent = Fixed rend + Additional rent

                = $(5+2x)

So, the expression for total cost is $(5+2x).

Carmen rent them for 4 hours. So, x=4 and the total cost is

Therefore, the total cost of 4 hours is $13.

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
