Ming plays a video game online when he sign up with the game site ming got 200 points ming earn 20 more points for each hour that he plays how many hours does ming have to play to get 500 points

a² + b²= c²

24² + 7² = c²

c= 25

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
