Answer:
- 40 popcorns and 90 pretzels sold.
============
Let the number of popcorns is x and pretzels is y.
Set up equations:
- x + y = 130
- 2.5x + 2y = 280
Solve by elimination, multiply the first equation by 2 and subtract from the second equation:
- 2.5x + 2y - 2x - 2y = 280 - 2*130
- 0.5x = 280 - 260
- 0.5x = 20
- x = 20/0.5
- x = 40
Find y:
- 40 + y = 130
- y = 130 - 40
- y = 90
I think it’s the last one
Answer:
30
Step-by-step explanation:
2700/90 = 30
27/9 = 3
100/10 = 10
3*10 = 30
14+x=84
x=70
The team lost 70 games.
84+70=x
154=x
The team played a total of 154 games.
The answer is the 3rd one
