What value of x makes this proportion true? 25/20 = x/4

x = 5

hope this helps :))

The value of x is 5.

Step-by-step explanation:

The given proportion is

In order to find the value of x for which the proportion is true, we can multiply both sides by 4.

On simplifying, we get

Thus, the value of x is 5.

Let us check if the proportion is true for x=5 or not.

Substitute x = 5 in the given equation.

Simplify the left hand side

We got a true result. Hence, the proportion is true for x=5.

Thus, the value of x is 5.
