Question

6. Kimi saw 13 animals in the barnyard.

Some were chickens and some were sheep.
Altogether there were 36 legs.
How many chickens and how many sheep did Kimi see?

Answer 1

Kimi saw 5 sheep and 8 chickens.

Explanation:

ok 13 animals so

c+s= 13

chicken= 2 legs

sheep = 4 legs

2c+4s = 36

factor out the 2 since all of them are even numbers

2(c+2s) = 2(18)

c+2s = 18

subtractfrom the second

c+2s = 18

- c+2s = 13

s = 5

c+5 = 13

13

- 5

= 8.

so 5 sheep and 8 chickens
