Three drink 4 cups of orange juice this is 2/5 of the total amount of juice that was in the container solve 2/5 X equals four to find the number of cups X of juice in the container how much juice was in the container

they used 313 gallons of paint

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
