Algebra.Com's Answer #335603 by chessace(471)![]() ![]() You can put this solution on YOUR website! Your 2nd equation is too far gone. \n" ); document.write( "The first one is close, you left out the 12%: \n" ); document.write( "Salt: .08x +.25(510-x)=.12*510 \n" ); document.write( "-.17x = -.13*510 \n" ); document.write( "x = (13/17)*510 = 13*30 = 390 L\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
