Algebra.Com's Answer #580400 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Fred needs 45 ml of 8% sucrose solution to do his science experiment. He needs to mix a 5% sucrose solution with some 15% sucrose solution to get the 8% solution he wants. How much of each should Fred use? \n" ); document.write( "----------------- \n" ); document.write( "Equation: \n" ); document.write( "sugar + sugar = sugar \n" ); document.write( "0.05x + 0.15(45-x) = 0.08*45 \n" ); document.write( "---- \n" ); document.write( "5x + 15*45 - 15x = 8*45 \n" ); document.write( "-10x = -7*45 \n" ); document.write( "x = 31.5 ml (amt. of 5% solution needed) \n" ); document.write( "45-x = 14.5 ml (amt. of 15% solution needed) \n" ); document.write( "------------- \n" ); document.write( "Please comment if this is a help. \n" ); document.write( "--------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "----------- \n" ); document.write( " |
