Algebra.Com's Answer #95865 by 067isa(13)![]() ![]() ![]() You can put this solution on YOUR website! the total lenght is 90 . we cut it into two pieces, the firt one is X and the second one is 20 more than the first cut/ \n" ); document.write( "that all you need to form an equation of the total length \n" ); document.write( "90= first cut + second cut \n" ); document.write( "90 = X + (X+20) \n" ); document.write( "90=2x+20 \" subtruct 20 form both sides \" \n" ); document.write( "70=2X divide both by 2 \n" ); document.write( "X= 35 which is the first cut \n" ); document.write( "this means the second cut is 20 +35= 55 \n" ); document.write( "55+35=90 right \n" ); document.write( " |
