Algebra.Com's Answer #50794 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Let x=number of quarts of water to be added\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The amount of pure alcohol before adding water = amount of pure alcohol after adding water. So our equation to solve is:\r \n" ); document.write( "\n" ); document.write( "6(.60)=(6+x)(.40) clear parens\r \n" ); document.write( "\n" ); document.write( "3.60=2.40+.4x subtract 2.40 from both sides\r \n" ); document.write( "\n" ); document.write( "3.60-2.40=2.40-2.40+.40x \n" ); document.write( "1.20=.40x \n" ); document.write( "x=3 qts-------------------------------answer\r \n" ); document.write( "\n" ); document.write( "CK\r \n" ); document.write( "\n" ); document.write( "6(.6)=9(.4)\r \n" ); document.write( "\n" ); document.write( "3.6=3.6\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps-----ptaylor\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
