Answer:
1 1/30 gallons, or 31/30 gallons of paint
Step-by-step explanation:
Before these fractions can be added together they have to have a common denominator. The Least Common Multiple of 2, 3, and 5 is 30, so
1/3 = 10/30 1/5 = 6/30 1/2 = 15/30
10/30 + 6/30 + 15/30 = 31/30, or 1 1/30
Step-by-step explanation:
EF = 4x - 15
FG = 3x - 7
EG = EF + FG = 20
so,
4x - 15 + 3x - 7 = 20
7x - 22 = 20
7x = 42
x = 6
EF = 4×6 - 15 = 9
FG = 3×6 - 7 = 11
Answer:

OR
x=\frac{3}{4} ±i\frac{\sqrt{39}}{4}\\
