Question

If the value of y varies directly with x, what is the value of x when y = 56?

A) x = 21
B) x = 24
C) x = 28
D) x = 32

Answer 1

To find the value of x when y = 56 in a direct variation, we can use the formula y = kx, where k is the constant of variation. However, since the constant of variation is not given in the question, the value of x cannot be determined.

Step-by-step explanation:

To find the value of x when y = 56 in a direct variation, we can use the formula y = kx, where k is the constant of variation. Since the value of y varies directly with x, we know that k is constant. Rearranging the formula to solve for x, we have x = y/k. Plugging in the values y = 56 and the constant k, we can find the value of x.

In this case, the constant of variation is not given in the question. Therefore, we cannot determine the value of x without the constant of variation. Hence, the correct answer is that the value of x cannot be determined.
