Algebra.Com's Answer #286350 by robertb(5830)![]() ![]() You can put this solution on YOUR website! 0.20x + 0.45(60 - x) = 0.30*60\r \n" ); document.write( "\n" ); document.write( "==> 0.20x + 27 - 0.45x = 18 \n" ); document.write( "==> -0.25x = -9 \n" ); document.write( "==> x = 35 L, the amount of the 20% solution, and \n" ); document.write( "60 - x = 25L, the amount of the 45% solution. \n" ); document.write( " |
