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 #2: The length of a rectangular room is 9 feet greater than its width. Which of the following equations represents the area (A) of the room?

A. A=9x

B. A=2x+2(x+9)

C. A=x(x+9)

D. A=x+(x+9)

Answer Explanation

we are asked to find the area of the room from the given information.

The first step is to find equation relating the length of the room to its width. If we let the width of the room to be x. Then,

Width of the rectangle= x

Length of rectangle = (x+9)

Area of the rectangle, A= Length*width = (x+9)*x

A=x(x+9)

Therefore, the area of the rectangular room is x(x+9).
