Question

If y is inversely proportional to x, and y = 60 when x = 3, what are the values of y when x = 5 and x = 4?

A
35 and 46


B
20 and 36


C
36 and 45


D
45 and 20

Answer 1

Option A 35 and 46

Explanation:

Answer 2

The correct answer is A. 35 and 46. When y is inversely proportional to x, it means that the ratio of x to y remains constant. In this case, when x = 3, y = 60, which means that the ratio of x to y is 3/60. Since the ratio is constant, we can use that ratio to find the values of y when x = 5 and x = 4. When x = 5, y = (3/60) x 5 = 35 and when x = 4, y = (3/60) x 4 = 46.
