I dunno what your question ask
Answer:
Step-by-step explanation:
So first it is useful to know that the area of any right triangle is 
or: 
Now we have the area and its base so we can fill in the equation:

All we have to do to solve it is divide by 8 (as 16 divided by 2 is 8) so:
96/8 = 12 so the height is 12
Answer:
Adult ticket: $7 Student ticket: $11
Step-by-step explanation:
First, we set up our equations.
x (adult ticket) y(student ticket)
For the first day, 11x + 3y = 110
For the second day, 3x + 6y = 87
Then we solve.
(-2)11x + 3y =110
Equals
-22x - 6y = -220
Add them
-22x - 6y = -220
3x + 6y = 87
This equals
-19x = -133
x = 7
Plug in to find y
3(7) + 6y = 87
21 + 6y = 87
6y = 66
y= 11
The y intercept is - 1
It is where the line touches or crosses the y axis
