Answer:
-8
Step-by-step explanation:
Y=mx+b, m=slope
in this case -8 is the m
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:
Congruent by SAS
Step-by-step explanation:
The three given sides of one triangle is shown to be equal to the corresponding sides of the other triangle.
This means that all threes sides of one are congruent to all corresponding sides of the other triangle.
By the Side-Side-Side Congruence Theorem, we can conclude that both triangles are congruent.
