a man 5 foot tall casts a 3 foot shadow. At the same time of day, a tree (Y) foot high casts an (X) feet shadow. What Is the Equation for this question?
\n" ); document.write( ":
\n" ); document.write( "This is a direct proportional relationship, we can write it:
\n" ); document.write( " $\"y%2Fx\"$ = $\"5%2F3\"$
\n" ); document.write( "Cross multiply
\n" ); document.write( "3y = 5x
\n" ); document.write( "divide both sides by 3
\n" ); document.write( "y = $\"5%2F3\"$ x, is the equation \n" ); document.write( "

\n" );
