White vinegar is a solution of acetic acid in water. There are two strenyhs of white vinegar- 5% solution and a 10% solution. How many ml of each solution must be mixed to make 50 ml of a 9% vinegar solution?
\n" ); document.write( "-------
\n" ); document.write( "active + active = active
\n" ); document.write( "0.05x + 0.10(50-x) = 0.09*50
\n" ); document.write( "-----
\n" ); document.write( "5x + 10*50 -10x = 9*50
\n" ); document.write( "-5x = -50
\n" ); document.write( "x = 10 ml (amt. of 5% solution needed)
\n" ); document.write( "50-x = 40 ml (amt. of 10% solution needed)
