1. What do x and y represent in this situation?
X stands for individual acts and y, group acts.
Besides that, In the system of equation, they represent the time for x, and the time for y.
2. Do you agree that your classmate set up the equations correctly? Explain why or why not.
Yes, that's right. Each scenario describes a different period in minutes, but each one respecting their different amounts (individual and group acts). Either for 120 minutes or 30 minutes length. And their sum totalizing the whole period.
3. Solving the system by Elimination

Answer:
An adult male Komodo dragon is

So, an adult male Komodo dragon is =(6×
) feet
feet
feet
=
feet.
feet.






Therefore the male is
feet longer than the mother.
