Algebra.Com's Answer #104316 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Let x=Amount of Brand A \n" ); document.write( "Then 21-x=Amount of Brand B\r \n" ); document.write( "\n" ); document.write( "Amount of peanuts in Brand A and B before the mixture takes place has to equal the amount of peanuts in the final mixture, so our equation to solve is:\r \n" ); document.write( "\n" ); document.write( "0.35x+0.25(21-x)=21*0.29 get rid of parens (distributive law) \n" ); document.write( "0.35x+5.25-0.25x=6.09 subtract 5.25 from each side\r \n" ); document.write( "\n" ); document.write( "0.35x+5.25-5.25-0.25x=6.09-5.25 collect like terms\r \n" ); document.write( "\n" ); document.write( "0.10x=0.84 divide each side by 0.10 \n" ); document.write( "x=8.4 oz---------------------------------Amount of Brand A needed \n" ); document.write( "21-x=21-8.4=12.6-----------------------------Amount of Brand B needed\r \n" ); document.write( "\n" ); document.write( "CK \n" ); document.write( "8.4*0.35+12.6*0.25=21*0.29 \n" ); document.write( "2.94+3.15=6.09 \n" ); document.write( "6.09=6.09\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
