Y varies directly as X. When X is 33, Y is 165. Find Y, when X is 14.
\n" ); document.write( ";
\n" ); document.write( "We know there is a constant (k) involved here:
\n" ); document.write( "y = k*x
\n" ); document.write( ":
\n" ); document.write( "When y = 165 and x = 33, we can write it:
\n" ); document.write( "33k = 165
\n" ); document.write( "k = $\"165%2F33\"$
\n" ); document.write( "k = 5
\n" ); document.write( ":
\n" ); document.write( "When x = 14
\n" ); document.write( "y = 5(14)
\n" ); document.write( "y = 70
\n" ); document.write( ":
\n" ); document.write( ";
\n" ); document.write( "Check it with a calc using proportion:
\n" ); document.write( "165/70 = 33/14 \n" ); document.write( "

\n" );
