Algebra.Com's Answer #121194 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! Let x = volume of original solution \n" ); document.write( ". \n" ); document.write( "\"amt of acid in original solution\" = \"amt of acid new solution\" \n" ); document.write( ".20x = .15(x+5) \n" ); document.write( ".20x = .15x + .75 \n" ); document.write( ".05x = .75 \n" ); document.write( "x = 15 liters (volume of original solution) \n" ); document.write( " |
