Answer:
Part a) variable x (the number of adult tickets sold) and variable y (the number of child tickets sold)
Part b) 
Part c) The number of adult tickets sold was 86
Step-by-step explanation:
Part a) Name a variable for the number of adult tickets sold and name a variable for the number of child tickets sold
Let
x -----> the number of adult tickets sold
y -----> the number of child tickets sold
Part b) Write an equation in two variables to model the problem
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for x


Part c) Using your equation in Part B, solve the problem and answer the question "how many adult tickets did Anne sell?" i
we have

Solve for x
Subtract 416 both sides



therefore
The number of adult tickets sold was 86

Step-by-step explanation:
step 1 is good: -5x + 8 = 7

-5x = 7 - 8
-5x = -1
step 3 : divide -5 on both sides
x = -1 / -5
x = 1/5
Answer:
m= 2 or 0.75
Step-by-step explanation:

} + 110m - 60 \\ 0 = - (40 {m}^{2} - 110m + 60) \\ 0 = - (5m - 10)(8m - 6) [/tex]
