Question

X is an element of the set 2.8, 3.7, 5.1, 14.0, 20.0 and 0.3x/0.25 is an integer. What is X?

A. 3.7

B. 5.1

C. 14.0

D. 20.0

Answer 1

To find the value of X, we need to solve the equation 0.3x/0.25 = n, where n is an integer. Depending on the value of n, the value of X will vary. Therefore, we cannot determine the exact value of X from the given options.

Step-by-step explanation:

To find the value of X, we need to solve the equation 0.3x/0.25 = n, where n is an integer.

Multiplying both sides of the equation by 0.25, we get 0.3x = 0.25n.

Dividing both sides of the equation by 0.3, we get x = 0.83n.

Since n is an integer, the value of X will be dependent on the value of n.

Therefore, we cannot determine the exact value of X from the given options.
