Algebra.Com's Answer #253449 by checkley77(12844)![]() ![]() ![]() You can put this solution on YOUR website! You have a mix of a 6% solution & an 8% solution. \n" ); document.write( "Where is the 10% solution??? \n" ); document.write( "Maybe you meant 10 liters? \n" ); document.write( "*********************************************** \n" ); document.write( ".08x+.06(10-x)=/.07*10 \n" ); document.write( ".08x+.6-.06x=.7 \n" ); document.write( ",02x=,7-.6 \n" ); document.write( ".02x=.1 \n" ); document.write( "x=.1/.02 \n" ); document.write( "x=5 ans. for the amount of 8% solutio used. \n" ); document.write( "Proof: \n" ); document.write( ".08*5+.06*5=.07*10 \n" ); document.write( ".04+.03=.07 \n" ); document.write( ".07=.07 \n" ); document.write( "5 liters of 6% if mixed with 5 liters of 8% yields 10 liters of a 7% solution. \n" ); document.write( " |
