Answer:
There's 15 cows and 35 chickens.
Step-by-step explanation:
Take 20 and multiply it by 2. The answer is 40. Then subtract 40 from 130. The answer will be 90. The cow has double the amount of legs than the chicken, so the cow is equivalent to 2 chicken. Divide 90 by 3. The answer is 30. Then divide 30 by 2 the answer is 15. Add 15 and 20 and the answer is 35 chickens. Divide 30 by 2 and the answer is 15.
You will get 35 chicken and 15 cows as your answer. Happy Election Night, and I hope this helps! ;)
