Algebra.Com's Answer #252854 by mananth(16946) You can put this solution on YOUR website! A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. Combining 112 ounces of Solution A with 28 ounces of Solution B gives 140 ounces of a mixture that is 40% salt. Combining 72 ounces of Solution A with 108 ounces of Solution B gives 180 ounces of a mixture that is 50% salt. \r \n" ); document.write( "\n" ); document.write( "... \n" ); document.write( "Shall we assume the question? \n" ); document.write( "... \n" ); document.write( "what is the strength of the original solutions? \n" ); document.write( "... \n" ); document.write( "let salt content of A be x% \n" ); document.write( "salt content of B be y % \n" ); document.write( "0.01x*112+0.01y*28= 140*0.4 \n" ); document.write( "1.12x+0.28y=56=0.......................1 \n" ); document.write( "0.01x*72+0.01y*108=0.5*180 \n" ); document.write( "0.72x +1.08y=90........................2\r \n" ); document.write( "\n" ); document.write( "solve the equations 1 &2 you will get \n" ); document.write( "A= 35% B= 60% \n" ); document.write( "... \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
