Step-by-step explanation:
Do this by setting up a form of system of equations.
a + s = 369
2a = s
Let’s use substitution to find the number of adult tickets!
a + 2a = 369
3a = 369
a = 123
So, there were 123 adult tickets sold!

Answer:
3 4/5 would be your answer in a mixed fraction...
The volume of the triangular prism is the Area of the base times the height
the area of the base is:
and the volume is:
now b=10 yards, a=20 yards, and V=600 yards^3
we clean the height
the answer is height = 6 yards
