Marsupial Mole

Congratulations, you got a golden mole as a pet! Unfortunately, the agents gave it to you in a cage with a cardboard bottom and Goldie--not a very clever name--burrowed through it during the night and escaped! The agents feel terrible about it so they've offered you a marsupial mole as a pet if you can complete the problems below before the timer runs out.

Good luck!

Reminder: Use * for multiplication, / for division, and ^ for exponent.

Problem 13: enter an equation with x

Problem 14: enter an equation with x & y

Problem 15: enter the value for x (just a number)

Problem 16: enter an equation with x

Problem 17: enter an equation with c

Problem 18: enter an equation for C with F in it (e.g. 2*F)

Problem 19: enter an equation for a with D & t in it

Time remaining to get a pet marsupial mole: minutes!
