I would graph with functions
find height and width then solve
a + b = c
Answer:
Vertically opposite angles.
Step-by-step explanation:
A line is a one-dimensional figure having no thickness and extends infinitely in both the directions.
Intersecting lines are the lines which intersect at one point.
Parallel lines which do not intersect at any point.
An angle is formed by two rays meeting at a common end point.
Vertically opposite angles are the angles formed opposite to one another at the intersection of two lines.
Vertically opposite angles are always equal.
Let a and c represent the numbers of adult and children's tickets sold, respectively. The system of equations will have one equation for revenue and one equation for number of tickets.
The revenue equation is
18a +9c = 4959
The number of tickets equation is
a + c = 319
_____
The solution can be found any number of ways. It is
(a, c) = (232, 87)
