\n" ); document.write( "determine how much of substance B is in the mixture
\n" ); document.write( ":
\n" ); document.write( "let x = the multiplier
\n" ); document.write( "then
\n" ); document.write( "2x = amt of A substance
\n" ); document.write( "and
\n" ); document.write( "5x = amt of B substance
\n" ); document.write( ";
\n" ); document.write( "2x + 5x = 50
\n" ); document.write( "7x = 50
\n" ); document.write( "x = 50/7
\n" ); document.write( "x = 7.143 is the multiplier
\n" ); document.write( "Find the amt of B substance
\n" ); document.write( "5*7.143 = 35.71 kg
