Algebra.Com's Answer #289459 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! To get 90ml of a 35% sugar solution, a 65% solution is mixed with a 20% solution. How much of the 65% solution is needed? \n" ); document.write( "----- \n" ); document.write( "Equation: \n" ); document.write( "sugar + sugar = sugar \n" ); document.write( "0.65x + 0.20(90-x) = 0.35*90 \n" ); document.write( "--- \n" ); document.write( "Multiply thru by 100 to get: \n" ); document.write( "65x + 20*90 - 20x = 35*90 \n" ); document.write( "45x = 15*90 \n" ); document.write( "x = (1/3)*90 \n" ); document.write( "x = 30ml (amt of 65% needed) \n" ); document.write( "90-x = 60ml (amt of 20% needed) \n" ); document.write( "=============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================ \n" ); document.write( " |
