Question

If m and n vary directly and m=3 when n=2, what is the value of m when n=4
no

Answer 1

m = 6

Explanation:

We know that m and n vary directly and that m = 3 when n = 2. How would we find m when n = 4? For starters, we can see that the value of n doubled (we know this because 2 doubled is 4), and since m and n vary directly, when n doubles, so does m so the answer is m = 3 * 2 = 6.
