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!

Step-by-step explanation:
(2)
cos(2θ) tan θ + sin θ = 0
tan θ (cos(2θ) + cos θ) = 0
tan θ = 0
θ = kπ
cos(2θ) + cos θ = 0
cos(2θ) = -cos θ
cos(2θ) = cos(π − θ)
2θ = π − θ + 2kπ
3θ = (2k + 1) π
θ = (2k + 1) π / 3
Therefore, θ = kπ or (2k + 1) π / 3.
(3)
2 cos² θ − 2 cos²(2θ)
Power reduction formula:
1 + cos(2θ) − (1 + cos(4θ))
cos(2θ) − cos(4θ)
Answer:
1/3 x (n-5)=2/3
Step-by-step explanation:
you have 1/3 times the difference(which is subtraction) of a number or N and 5 and the word "IS" means equals in algebra and then just put 2/3 at the end so 1/3 x (N-5)=2/3
