Capacity of the tank = 45 gallon
At the beginning of Oct., amount of oil in the tank = 45*0.8 = 36 gallons
At the end of Oct., amount of oil in the tank = 45*1/3 = 15 gallons
So, amount of oil used during Oct = (36-15) = 21 gallons
The correct answer is: x ≥1
Answer:
x(3+28y)
Step-by-step explanation:
21x-18x+28xy
3x+28xy
x(3+28y)
22 x 85 = (20+2)*85= 20*85+ 2*85 = 1700 + 170 = 1870
