20-11
Answer:
No solution.
Step-by-step explanation:
y + 3x - 4y = 0 + 0.75x
- 3y + 3x = 0 + 0.75x
- 3y + 3x - 0.75x = 0 + 0.75x - 0.75x
- 3y + 2.25x = 0
8 quarts = 32 cups
So we have a ratio of 32 : 3/4 cups
And the equal ratio of 4: x
So to solve for x, divide 3/4 by 8.
3/4 divided by 8 = 3/4 •1/8 = 3/32 of a cup of green paint.
