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.
0.000027/0.000009 = 3.
You're right because it's a scientific or try to plug that number into a scientific calculator.
ans: 70 ...( it is by ; 180-110) because of straight angle= 180...........
I hate questions like this. It's like wishing for more wishes.
