Your friend says there is no way that a mother and daughter could do the same thing. Use what you know about the different types of variation to figure out how a mother and child could balance. The values gave to me are

\n" ); document.write( "The second question is The lever tool helps ring values that will balance your seesaw but it has a limited range of precision. Use your graph to estimate a coordinate (W,D) that balances your seesaw. please show correct substitution and verification I really don't get this at all
