the first contest
private message me the answers you get...
1. If x=2, y=3, and z=12, what is xyz+xz? 2. If there was a class of 923 people who had a test, and whoever score above the average get a treat, what is the highest number of people who can get a treat? There is no rounding involved, the average can be a decimal with a billion decimal places for all i care. 3. If someone wakes up at x a.m., and goes to sleep at x p.m., how long does he stay up? 4. If x=y, what is x to the power of xy?x and y do not equal 0. 5. What is the yintercept of the line x=5y17? These could be hard, but its a waste of time to have an easy contest!
