Algebra.Com's Answer #383628 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! a chemist must mix 6 liters of a 30% acid solution with some of an 80% solution to get a 50% acid solution. How many liters of the 80% solution should be used.\r \n" ); document.write( "\n" ); document.write( "I think I have the equation set up correctly:\r \n" ); document.write( "\n" ); document.write( "0.80x + 0.30*6=0.50(x+5) \n" ); document.write( "-------------- \n" ); document.write( "0.8x + 0.30*6 = 0.50*(x + 6) not x+5, you got it right o/w \n" ); document.write( "Solve for x \n" ); document.write( "Multiply by 10 to eliminate fractions \n" ); document.write( "8x + 18 = 5x + 30 \n" ); document.write( "x = 4 liters\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
