Let a, b, c represent the numbers of $8, $10, and $12 tickets sold, respectively. The problem statement gives rise to three equations:
- a + b + c = 500
- 8a +10b +12c = 4700
- a + b - 4c = 0
Solving these equations by your favorite method gives ...
... (a, b, c) = (250, 150, 100)
250 $8 tickets, 150 $10 tickets, and 100 $12 tickets were sold.
_____
After you subtract the 3rd equation from the first to find 5c=500, you can substitute c=100 into the first two equations to get two equations in two unknowns. You know several ways to solve such equations, including elimination, substitution, and graphing, at least. Cramer's method is another viable choice.
Choice C Because it's either that one or the top one because x = hotdogs and the top one the numbers are flipped so choice C
The height of the tree is 42.
Answer:
Depends on the angel needed, I'll provide all answers
Step-by-step explanation:
Angel A is 93, because a straight line has an angel total of 180, so in order to find angel A you would just need to subtract
180-87 = 93
Angel B is 87, because angels opposite each other have the same value.
The Angel without a character would be 93 for the same reason :3
