You can put this solution on YOUR website!
Question #2, the acid mixture:\r
\n" ); document.write( "\n" ); document.write( "x and y, the volume of low and high concentration acids
\n" ); document.write( "Solve this system:
\n" ); document.write( "\"x%2By=50\"
\n" ); document.write( "\"%28x%2A0.06%2By%2A0.10%29%2F50=0.0728\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The rational one rearranges to 6x+10y=50*7.28, then 6x+10y=364, then 3x+5y=182
\n" ); document.write( "So an easier but equivalent system to solve is
\n" ); document.write( "\"x%2By=50\"
\n" ); document.write( "\"3x%2B5y=182\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You might continue by taking the x+y=50 and multiply both sides by 3, and subtracting the equation from the \"182\" equation, and find a value for y. \r
\n" ); document.write( "\n" ); document.write( "3x+5y=182
\n" ); document.write( "-(3x+3y)=-(150)
\n" ); document.write( "________________
\n" ); document.write( "0+2y=32
\n" ); document.write( "y=16.
\n" ); document.write( "\"highlight%28y=16%29\" cubic centimeter for the 10% acid, so....
\n" ); document.write( "
\n" );
