\n" ); document.write( "Hi
\n" ); document.write( "making 10 tons of concrete
\n" ); document.write( "Let x and (10-x) represent the amount of 65% and 17% cement mixtures respectively
\n" ); document.write( "Question states***Mixing to form 10 tons of 36.2% mixture
\n" ); document.write( " .65x + .17(10-x) = .362*10
\n" ); document.write( " .48x = .192*10
\n" ); document.write( " x = .192*10/.48
\n" ); document.write( " x = 4 tons of the 65% mixture needed\r
\n" ); document.write( "\n" ); document.write( "CHECKING our Answer***
\n" ); document.write( ".65*4 + .17*6 = 3.62
\n" ); document.write( " \n" ); document.write( "
