Hello, \n" ); document.write( "Let x be the total perimeter,then we can set up an equation. \n" ); document.write( "11 + 2/5(x) + 1/2(x) = x Let's multiply 10 so to get rid of the fractions. \n" ); document.write( "110 + 4x + 5x = 10x Now, subtract 9x from both sides. \n" ); document.write( "110 = x This gives us the total perimeter. \n" ); document.write( "11 cm is one side (given) \n" ); document.write( "44 cm is another side \n" ); document.write( "55 cm is the other side These should add up to 110 cm \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.com \n" ); document.write( " \n" ); document.write( " |
