Answer:
45 tickets for the matinee were sold
Step-by-step explanation:
let m represent the number of matinee tickets sold and
let e represent the number of evening tickets sold.
Create a system of equations and solve for m
m + e = 130 → (1) ( total ticket sales )
6m + 10e = 1120 → (2) ( income from tickets sold )
multiplying (1) by - 10 and adding the result to (2) will eliminate e
- 10m - 10e = - 1300 → (3)
add (2) and (3) term by term to eliminate e
(6m - 10m) + (10e - 10e) = 1120 - 1300
- 4m + 0 = - 180
- 4m = - 180 ( divide both sides by - 4 )
m = 45
the number of matinee tickets sold was 45
Answer: You need to separate the variable (A) from the rest of the equation.
Step-by-step explanation:
Simplify and move everything except the variable
2x2 = -6 + 8a >>> 4 = -6 + 8a >>> 10 = 8a
Then, divide both sides by the amount of A (8)
10 / 8 = 1.25
8 / 8 = 1
1.25 = A
