A delivery truck weighs 4 tons. One gallon of cement weighs about 20 pounds. The truck is carrying 300 gallons of cement. What is the total weight of the truck and cement, to the nearest pound? (1 ton = 2,000 pounds) A.
2,000 pounds

B.
6,000 pounds

C.
8,000 pounds

D.
14,000 pounds

Calculate total weight of cement:

300 gallons x 20 lbs per gallon = 6000 pounds.

1 ton = 2000 pounds:

Weight of truck in pounds: 4 Toni x 2000 = 8,000 pounds

Total weight = 8000 + 6000 = 14,000 pounds

The answer is D.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
