Suppose y varies directly with x, and y =25 when x = 140. What is the value of x when y = 36?

1 answer

We can set up a proportion to solve for the value of x when y = 36:

y/x = 25/140

Cross multiplying, we get:

25x = 140 * y

Plugging in y = 36, we get:

25x = 140 * 36

Simplifying, we get:

25x = 5040

Dividing both sides by 25, we get:

x = 201.6

Therefore, the value of x when y = 36 is approximately 201.6.
