Answer:
Step-by-step explanation:
If we let 'a' represent the price of an adult ticket, and 's' represent the price of a student ticket, the two sales can be described by ...
5a +4s = 85
5a +2s = 55
Subtracting the second equation from the first gives ...
(5a +4s) -(5a +2s) = (85) -(55)
2s = 30 . . . . simplify
s = 15 . . . . divide by 2
Substituting this into the second equation, we have ...
5a +2(15) = 55
5a = 25 . . . . subtract 30
a = 5 . . . . . divide by 5
Each adult ticket sold for $5; each student ticket sold for $15.
The square root of 9 is 3
Answer:
x = -1 ; y = 1
Step-by-step explanation:
x = -1
y = 1
Plug in the corresponding numbers to the corresponding variables:
y < -x + 1
(1) < -(-1) + 1
1 < 1 + 1
1 < 2 (True)
y > x
1 > -1 (True).
