Suppose y varies directly with x, and y = 24 when x = 8. What is the value of y when x = 10?

30
80
240

Answer 1

Since y varies directly with x, we can set up the proportion:

y / x = k

where k is the constant of variation.

We can solve for k by substituting the given values:

24 / 8 = k
k = 3

Now, we can find the value of y when x = 10 by substituting into the equation:

y / 10 = 3
y = 30

Therefore, the value of y when x = 10 is 30.
