Answer:
1) yes
2) no
3. yes
Step-by-step explanation:
(plz make me brainliest)
Set x as adult tickets.
Set y as children's tickets.
x + y = 15
30x + 20y = 270
Solve for x in the first equation.
x + y = 15
x = 15 - y
Plug this into the second equation.
30x + 20y = 270
30(15 - y) + 20y = 270
450 - 30y + 20y = 270
450 - 10y = 270
-10y = -180
y = 18
If there is 18 childrens tickets, there should be -3 adult tickets.
This is impossible, and this impossible answer occured because the question is written wrong.
There are a total of 15 tickets
The smallest costing ticket is the childrens ticket, which costs 20$.
If he only bought children tickets, this would be 20x15 which is 300$.
300$ is over 270$, which makes the question impossible.
Answer:
The answer to the question provided is y = -3x - 12.
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟

❃Incase you also forgot, what the slope formula is ☟

➊ First: We are going to be solving for the slope.

➋Second: We find the y-intercept.

➌Third: Plug in.

It's a bit hard to explain but I hope this helps
