Substitute into width = 3x. \n" ); document.write( "width = 3(5) = 15 units\r \n" ); document.write( "\n" ); document.write( "2. Number of pieces of rope that can be cut = \n" ); document.write( "Therefore, 28, which is the greatest number of pieces of rope that can be cut from a piece of 8-meters-long rope. \n" ); document.write( " |
