Answer:

$8.13

Step-by-step explanation:

Suzanne needs material for her school project and so, she buys 3¼ yards of material at a rate of $2.50 a yard.

To find the total cost of the material she bought, we will multiply the amount of yard she bought by the price of each yard. That is:

C = 3¼ * 2.50

C = 13/4 * 2.50

C = $8.125

Rounding up to the nearest cent, the total cost of the material. She bought for her school project is $8.13 or $8 and 13¢.

Which value of x makes the equation 2/3x-3=11 true?
harkovskaia [24]

Answer:

x = 21

Step-by-step explanation:

To see for what value of x is the equation true, we have to solve x.

\displaystyle \frac{2}{3} x - 3 = 11\\\\Adding \ 3 \ to \ both \ sides\\\\\frac{2x}{3} = 11 + 3\\\\\frac{2x}{3} = 14\\\\Multiply \ 3 \ to \ both \ sides\\\\2x = 14 \times 3\\\\2x = 42 \\\\Divide\ both\ sides\ by\ 2\\\\x = 42/2\\\\x = 21\\\\For \ x = 21\ the \ given \ equation \ is \ true.\\\\\rule[225]{225}{2}

Hope this helped!
