:
\n" ); document.write( " m varies directly with n; m = 144 when n = 8
\n" ); document.write( ":
\n" ); document.write( "The equation:
\n" ); document.write( " m = n*k
\n" ); document.write( ":
\n" ); document.write( "Subsitute for m & n, find k
\n" ); document.write( "144 = 8k
\n" ); document.write( "144/8 = k
\n" ); document.write( "k = 18
\n" ); document.write( ":
\n" ); document.write( "Check it when n = 8
\n" ); document.write( "m = 8 * 18
\n" ); document.write( "m = 144\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
