A certain shade of pink is created by adding 3 cups of red paint to 12 cups of white paint. a. how many cups of red paint should be added to 1 cup of white paint?

The number of white cups that should be added to 1 cup of red paint is 4.

If there are 3 cups of red and 12 cups of white and we are finding the amount for white cups when there is 1 cup of red, we divide.

3/1 = 3.

We have to divide the 12 cups of white by 3.

12/3 = 4.

You need 4 cups of white.

there is no question content here, but you for the free points! : d

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
