Step-by-step explanation:

3x - 3 - 4x - 2 = 8x - 8

Solving like terms

-x - 5 = 8x - 8

Bringing like terms on one side

-5 + 8 = 8x + x

3 = 9x

3/9 = x

Mimi needs eleven 18-inch pieces of rhinestone ribbonShe purchased 5 yards of the ribbon shown at the rightWhat is the total amo

GalinKa [24]

Answer:

5.5 yards.

Step-by-step explanation:

We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.

First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:

$\text{Amount of total ribbon in inches}=11\times 18\text{ inches}$

$\text{Amount of total ribbon in inches}=198\text{ inches}$

We know that 1 yard equal to 36 inches. To convert 198 inches into yards, we will divide 198 by 36 as:

$\text{Amount of total ribbon in yards}=198\text{ inches}\times \frac{1\text{ Yard}}{\text{36 inches}}$

$\text{Amount of total ribbon in yards}=\frac{1\text{19 Yard}}{36}$

$\text{Amount of total ribbon in yards}=5.5\text{ Yards}$

Therefore, the total amount of ribbon that Mimi needs is 5.5 yards.
