To get the perimeter around a triangle, you simply add up all the lengths of the sides.

5x - 2 + 4x + 3 + 2x - 3

Then combine like terms.

5x - 2 + 4x + 3 + 2x - 3 = 11x - 2

So, 11x - 2 is the answer.

The cost of renting roller blades is $4 plus $3.50 for each hour that the roller blades are rented. Write an expression to repre
Pavel [41]

Answer:

The expression is equal to 3.50h+4

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

y=mx+b

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

m=\$3.50\ per\ hour

The y-intercept is equal to

b=\$4 ----> value of y when the value of x is equal to zero

substitute

y=3.50x+4

For x=h hours

substitute

y=3.50h+4

13/2 divided by 3/4
Juliette [100K]

Answer: 26/3

Step-by-step explanation: When dividing by a fraction, we can change

the division sign to multiplication and flip the second fraction.

So 13/2 ÷ 3/4 means the same thing as 13/2 · 4/3.

So when dividing by a fraction, we can just multiply

by the reciprocal of that fraction or that fraction flipped.

Next we cross-cancel.

4 and 2 reduce to 2 and 1.

Multiplying across the numerator and denominators we have 26/3.
