Answer:
hmmm
Step-by-step explanation:
If 1 gallon = 3.785 litres
Then, 10 gallons = 37.85 litres
y = - 5/6 x + 1
y = mx + b m: slope b: y intercept
point (6 , -4) x = 6 y = -4
b = y - mx = -4 - ((-5/6) x 6) = - 4 + 5 = 1
equation: y = - 5/6 x + 1
14.1
3x-10+25+x+15=180
4x+30=180
4x=180-30
4x=150
x=37.5
