# If y varies inversely as x, and y=14 when x=7, how do you find y when x=10?

To find y when x=10, we can use the inverse variation formula: y = k/x.

First, we need to find the constant of variation, k. We can do this by substituting the given values into the formula.

When y=14 and x=7, we have: 14 = k/7.

To solve for k, we can multiply both sides of the equation by 7: 14 * 7 = k.

Simplifying, we get: k = 98.

Now that we have the value of k, we can substitute it back into the inverse variation formula and solve for y when x=10.

Plugging in x=10 and k=98, we have: y = 98/10.

Simplifying, we find that y = 9.8.

Therefore, when x=10, y is equal to 9.8.
