Answer:
Step-by-step explanation:
Let x be the portion of 60%
180 - x is the portion of 40%
0.60x + 0.40(180 - x) = 0.55(180)
0.60x + 72 - 0.40x = 99
0.20x = 27
x = 135
180 - 135 = 45
First brand = 45 gallons of 40%
Second Brand = 135 gallons of 60%

7)
17x + 3 = 54
17x = 51
x = 3
4y - 3 = 57
4y = 60
y = 15
8)
4x - 3 = 45
4x = 48
x = 12
180 - 45 - 41 = 84
11y + 6 = 94
11y = 88
y = 8
