n Ms. Ayala's class, 45% of the students regularly play video games. If 18 students regularly play video games, how many students are in the class?

40 students

Explanation:

So its 45% out of 100%. multiply 18 by 100% and divide it by 45 and you get 40

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
