Algebra.Com's Answer #114783 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Let x=amount of nuts needed\r \n" ); document.write( "\n" ); document.write( "Now we know that the value of the nuts(3x) and candy(6*30) before they are mixed has to equal the value of the nuts and candy after they are mixed(5*(30+x)), ok? ($ are understood) So, our equation to solve is: \n" ); document.write( "3x+6*30=5(30+x) get rid of parens and simplify\r \n" ); document.write( "\n" ); document.write( "3x+180=150+5x subtract 150 and also 3x from each side\r \n" ); document.write( "\n" ); document.write( "3x-3x+180-150=150-150+5x-3x collect like terms\r \n" ); document.write( "\n" ); document.write( "30=2x divide each side by 2\r \n" ); document.write( "\n" ); document.write( "x=15 lb-------------amount of nuts needed\r \n" ); document.write( "\n" ); document.write( "CK \n" ); document.write( "3*15+6*30=5*45 \n" ); document.write( "45+180=225 \n" ); document.write( "225=225\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
