Algebra.Com's Answer #325807 by Theo(13342)![]() ![]() You can put this solution on YOUR website! x = 2y \n" ); document.write( "y = 4z \n" ); document.write( "2z = w \n" ); document.write( "w <> 0 \n" ); document.write( "x/w = ????? \n" ); document.write( "x/w = 2y/2z \n" ); document.write( "y = 4z, so we can replace y with 4z to get: \n" ); document.write( "x/w = (2*4z)/2z) = 8z/2z = 4 \n" ); document.write( "your answer should be 4. \n" ); document.write( "let's do it again to make sure. \n" ); document.write( "the equation we want is x/w \n" ); document.write( "we know that x = 2y so we substitute 2y for x to get: \n" ); document.write( "2y / w \n" ); document.write( "we know that w = 2z so we substitute 2z for w to get: \n" ); document.write( "2y / 2z \n" ); document.write( "we know that y = 4z, so we substitute 4z for y to get: \n" ); document.write( "2*4z / 2z \n" ); document.write( "the z cancels out and the 2 cancels out and we are left with 4. \n" ); document.write( "that's your answer.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
