133 adult tickets were sold.
Step-by-step explanation:
Given,
Total tickets sold for school play = 399
Let,
x represent the number of children tickets sold.
y represent the number of adult tickets sold.
According to given statement;
x+y=399 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 3
133 adult tickets were sold.

Answer:
slope = 0
Step-by-step explanation:
y = - 
is the equation of a horizontal line parallel to the x- axis.
Since it is parallel to the x- axis the slope = 0
Thus any line parallel to it will have a slope = 0
The Law of Cosines would be your best bet here, since the unknown side is opposite the known angle 110 degrees.
|AC|^2 = (8 in)^2 + (23 in)^2 - 2(8 in)(23 in)*cos 110 degrees
= 64 in^2 + 529 in^2 - (368 in^2)*(-0.342)
= 593 in^2 + 126 in ^2 approximately
= 719 in^2 approximately
Then the length of side AC is approx. √(716 in^2) = 27 in
