Answer:
26 child tickets
Step-by-step explanation:
4c = a to make the adult tickets equal to the child tickets multiply the child tickets by 4. then use substitution.
6.10c + 9.90(4c) = 1188.20
6.10c +39.6c = 1188.20
45.7c = 1188.20
c = 26
Answer:
-47
Step-by-step explanation:
that's the correct answer
The answer is d) none because substituting -1/4x + 5/3 for y in the first equation gives 3x - 3x + 5/3 = 20 so 5/3 = 20 which is not true.
