Sorry, I only know 8, 9, and 10.
8. This can be anything, but my guess would be 40 - 20 = 20
9. 3, because 3 x 3 = 9.
10. 7, because 7 x 4 = 28.
Hope this helped!
12 plus 18 over 3 so it is 12+6 which is 18 So 18 is your final answer

Answer: an adult ticket cost $8 and a student ticket cost $4
Step-by-step explanation:
Let x represent the cost of one student ticket.
Let y represent the cost of one adult ticket.
A drama club earns $1040 from a production. It sells a total of 64 adult tickets and 132 student tickets. It means that
132x + 64y = 1040 - - - - - - - - - -1
An adult ticket costs twice as much as a student ticket. It means that
y = 2x
Substituting y = 2x into equation 1, it becomes
132x + 64 × 2x = 1040
132x + 128x = 1040
260x = 1040
x = 1040/260 = 4
y = 2x = 2 × 4
y = 8
