Question

Value of m varies directly as value of n and n=5 when m=12. What is n when m=18?
I think n = 11, but i am not sure.
Thanks, Paula

Answer 1

Answer:

Direct variation

m×n

m = kn

k=m/n. when m = 12,n =5

k=12/5

finding n. when m=18

m=kn

divide both sides by k

n=m/k

n=18/12/5

n=90/12

n=15/2
