Joe’s uncle is eight less than four times Joe’s age. Which of the equations represents Joe’s uncle’s age (u) as it relates to Joe’s age (k)?
A. u=8-4k
B. k=4u-8
C. k=8-4u
D. u=4k-8
We are asked to form an equation to find Joe’s uncle’s age to the age of Joe.
First, we find Joe’s age which is k. We know that Joe’s uncle’s age is four times that of Joe less 8. Then,
Joe’s uncle’s age, u = 4k-8.
Thus, the age of Joe’s uncle is u=4k-8.
Therefore, the Correct Answer is d.

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.
