Which of the following is the weight of the cargo in a truck if 3/5 of the cargo weighs 615 pounds (lb)?

A. 1025 lb

B. 1320 lb

C. 1548 lb

D. 788 lb

Answer Explanation:

In this problem, we assume the truck carry a whole cargo to carry. Thus, total weight is found by dividing 615 lb by 3/5. Thus,

We change the division sign to product and multiply 615 by reciprocal of 3/5. Then,

(615 * frac{5}{3} = 1025 lb)

The weight of the cargo in the truck will be 1025 lb.

Therefore, the Correct Answer is A.

Q #1: (frac{[2 (8 + 2 * 6)]}{(16 div 2)} = frac{40}{8} = 5) Simplify the expression above. Which of the following is correct?

A. 6

B. 2

C. 5

D. 3

Answer Explanation

We follow the order of operations to solve the given expression.

First, we start with the numerator and solve

[2(8+2*6)]

We start with multiplication in inner brackets, 2*6=12. The expression becomes

[2(8+12)]

Then, we conduct the addition of 8+12=20. Then, the expression yields

[2(20)] = 2*20 = 40

Now, we solve for denominator, which is 16/2=8.

Thus, the expression is reduced into

(frac{[2 (8 + 2 * 6)]}{(16 div 2)} = frac{40}{8} = 5)

The expression reduces into 5.
