Answer: F
Step-by-step explanation:
- This does not have infinitely many solutions (adding the equations, we get a fixed value of x)
- This has no solutions (the left hand sides are the same but the right hand sides have different values)
- This has one solution (the first equation givess a fixed value for x)
- This has no solutions (same reason as 2)
- This has one solution (same reason as 3, just the second equation instead of the first)
- This has infinitely many solutions (multiplying both sides of the top equation by -2 gives the bottom equation).
Answer:
646 child tickets are sold
Step-by-step explanation:
Let c represent the number of child tickets sold. Then (c-186) is the number of student tickets sold, and (c+234) is the number of adult tickets sold. The total number sold is ...
(c -186) + c + (c+234) = 1986
3c +48 = 1986 . . . simplify
c + 16 = 662 . . . . divide by 3
c = 646 . . . . . . . . . subtract 16
The number of child tickets sold is 646.
