You can put this solution on YOUR website!
so yx=k therefore 1.5(8)=12 so 12 is our constant k\r
\n" ); document.write( "\n" ); document.write( "now if you have x=20 and want to find y --->you must multiply x time y and make it equal to our constant. hence 20(y)=12(our constant)\r
\n" ); document.write( "\n" ); document.write( "\"highlight%28y=12%2F20=3%2F5%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "another way of doing this is to set up a proportion of \"y%5B1%5D%2Fy%5B2%5D=x%5B2%5D%2Fx%5B1%5D\"
\n" ); document.write( "an inverted relationship proportion
\n" ); document.write( "
\n" );
