2/3(9x-6)=1/4(12-4x)

Studentka2010 [4]

Answer:

x = 1

Step-by-step explanation:

$\frac{2}{3}$ (9x - 6) = $\frac{1}{4}$ (12 - 4x) ← distribute parenthesis on both sides

6x - 4 = 3 - x ( add x to both sides )

7x - 4 = 3 ( add 4 to both sides )

7x = 7 ( divide both sides by 7 )

x = 1

If 4 quarts of organic grapes cost $20 how many quarts can you purchase for one dollar

Eva8 [605]

Answer:

4/5 of a quart

Step-by-step explanation:

Set this up as a proportion. First of all we know that 4 quarts of organic grapes cost $20, so 4x = 20. Divide and you get that x = 5 meaning 1 quart equals 5 dollars. Now if we scale this down a bit and divide by 5, we end up with 4/5 of a quart = 1$.

Hope this helped (:
