Algebra.Com's Answer #786516 by VFBundy(438)![]() ![]() You can put this solution on YOUR website! First piece = x \n" ); document.write( "Second piece = 2x - 6 \n" ); document.write( "Third piece = x + 5 \n" ); document.write( "Fourth piece = (2x - 6)/2 = x - 3 \n" ); document.write( " \n" ); document.write( "(x) + (2x - 6) + (x + 5) + (x - 3) = 96 \n" ); document.write( " \n" ); document.write( "5x - 4 = 96 \n" ); document.write( " \n" ); document.write( "5x = 100 \n" ); document.write( " \n" ); document.write( "x = 20 \n" ); document.write( " \n" ); document.write( "The fourth piece is (x - 3) inches long. Plugging in x = 20, that comes out to 17 inches. |
