Answer:
n = 7.5
Step-by-step explanation: Each side was multiplied by 3 to get the red triangle. So multiply 2.5 x 3 and it equals 7.5 which is n
You can see that 5 went to 15, and 5.5 went to 16.5. The only way to get there was to multiple each side by 3.
5x3=15
5.5x3=16.5
2.5x3=7.5

Area of a triangle = 1/2 x base x height
Area = 1/2 x 8.7 x 8.6
Area = 37.41 square feet
x = students = $10
y = non students = $12
total tickets = 150
Equations
x + y = 150
10x + 12y = 1440
x = 150 - y
10(150 - y) + 12y = 1440
1500 - 10y + 12y = 1440
2y = 1440 - 1500
2y = -60
y = -60/2
y = 30
x = 150 -
