Question 68452
m varies directly with n; m = 144 when n = 8.
"m varies directly with n" means m=kn (k is the constant of proportionality)
let m=144 and n=8 and solve for k
{{{144=k(8)}}}
{{{144/8=k(8)/8}}}
{{{18=k}}}
Therefore, letting k=18, the formula is:
{{{highlight(m=18n)}}}
Happy Calculating!!!
