Carmen rents roller skates for $5 plus $2 for every hour she uses them. Define the variable and write an expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.

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.

pleaze mark brainliest!

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
