Algebra.Com's Answer #276073 by gwendolyn(128)![]() ![]() You can put this solution on YOUR website! If the weights are directly proportional, the ratio (weight on earth):(weight on mars) will always be the same. So, using the data points we are given:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Multiply both sides by W to get it out of the denominator: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Cross out the Ws on the left because they are just multiplying by 1: \n" ); document.write( "2.5*W = 98\r \n" ); document.write( "\n" ); document.write( "Divide both sides by 2.5 to solve for W: \n" ); document.write( " \n" ); document.write( "Cross out the 2.5/2.5 and do the division: \n" ); document.write( "W = 39.2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
