etc

Answer 2

Answer:

a) a + c = 29 (1)

10a + 6c = 222 (2)

b) a = 12, c = 17

c) 12 adults and 17 children visited the zoo

Step-by-step explanation:

a)

a + c = 29 (1)

10a + 6c = 222 (2)

b) from (1) a = 29 - c

Plug in (2) 10(29 - c) + 6c = 222

290 - 10c + 6c = 222

-4c = 222 - 290

-4c = -68

c = (-68)/(-4)

c = 17

a = 29 - c

a = 29 - 17

a = 12

c) 12 adults and 17 children visited the zoo
