Answer:
C is the most reasonable answer because to add the system of equations together, you must make sure that one of the terms (whether it be the x or y value) can cancel out.
Step-by-step explanation:
Answer:
62390
Step-by-step explanation:
you have to round up if it's 5 or more and round down if it's less.

5 because it’s a double negative which offsets the answer to be positive 5
Answer:
132 people bought balcony tickets and 450 bout ground tickets
Step-by-step explanation:
let x be balcony and y for ground
x+y=582
15x+10y=6480 solve by adding(subtracting)/eliminating process
multiply first equation by 15 to eliminate x:
15x+15y=8730
15x+10y=6480 subtract
15x+15y-15x-10y=8730-6480
5y=2250
y=2250/5=450
x+y=582
x=582-450=132
