You can put this solution on YOUR website!
m varies directly with n; m = 144 when n = 8.
\n" ); document.write( "\"m varies directly with n\" means m=kn (k is the constant of proportionality)
\n" ); document.write( "let m=144 and n=8 and solve for k
\n" ); document.write( " $\"144=k%288%29\"$
\n" ); document.write( " $\"144%2F8=k%288%29%2F8\"$
\n" ); document.write( " $\"18=k\"$
\n" ); document.write( "Therefore, letting k=18, the formula is:
\n" ); document.write( " $\"highlight%28m=18n%29\"$
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
