If y is directly proportional to x and y = 10 when x =2 , find the value of x when y = 60.

12

Step-by-step explanation:

When we see the words "y is directly proportional to x", we immediately think of the direct proportion formula y = kx , where k is a constant.

We are given that y = 10 and x = 2, so we want to find the constant by plugging these values into the formula:

y = kx

10 = k * 2

k = 5

So, we now have the equation y = 5x. We want to find x when y = 60, so just plug 60 in for y in our new equation:

y = 5x

60 = 5x

x = 12

Thus, the answer is x = 12.

Hope this helps!
