Question

20

Answer 1

Answer:

69 - 52 = g

(g = 17)

Step-by-step explanation:

69 [total students] - 52 [no role] = g [those who got in]

69 - 52 = g            {simplify/combine like terms}

17 = g

g = 17

So, 17 students will be in the play

(could also be modeled as 52 + g = 69)

(this is because the only possibility for each student is to either not get in, or get in. So, if we add these two values up, we get the total number of students who auditioned).

(if you want to model the equation as such:

52 + g = 69

- 52          -52   {subtract 52 from both sides to isolate g}

g = 17)

Answer 2

69 - 59 = g
g= 17
So the answer will be most likely 17 students
