Algebra.Com's Answer #46646 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Let x=length of two shorter pieces \n" ); document.write( "Then 2x+5=length of the long piece\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now we know that the length of all three pieces equals 26 ft so our equation to solve is:\r \n" ); document.write( "\n" ); document.write( "x+x+(2x+5)=26 \n" ); document.write( "4x=21 \n" ); document.write( "x=5.25ft\r \n" ); document.write( "\n" ); document.write( "2x+5=2(5.25)+5=10.50+5 =15.50ft for longest piece\r \n" ); document.write( "\n" ); document.write( "Hope this helps----ptaylor\r \n" ); document.write( "\n" ); document.write( "ck\r \n" ); document.write( "\n" ); document.write( "15.50+10.50=26 ft\r \n" ); document.write( "\n" ); document.write( "2x+5=2(5.25)+5=15.50ft\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
