For this case, the first thing we must do is define variables.
We have then:
x: cost of each bag of popcorn
y: cost of each drink
writing the system of equations we have:
9x + 9y = 117
x + 3y = 23
Solving the system of equations we have:
x = 8 $
y = 5 $
Answer:
a system of equations that can be used to find the price of one bag of popcorn and the price of one drink is:
9x + 9y = 117
x + 3y = 23
The price of a bag of popcorn is $ 8.
A straight line is equal to 180, anything going all around is 360 if the angles are crossing eachother then the angles across from eachother are equal so x=z
X+150=180, Im not good at explaining sorry, but i know what I’m doing yk just lmk sorry if it didn’t help
-5 Subtract 8 from -12 and divide -20 by 4 and get -5
Answer:
Step-by-step explanation:
(1)

(2)
The initial condition is 
(3)
Infinitely many.
F-1(x) = (3x + 5) / 3
f-1(3) = (9 + 5) / 3 = 14/3
