Question

In a stable there are chickens and rabbits; altogether there are 18 ears and 66 legs; if C is the number of rabbits and P the number of chickens, the system of equations that allows us to answer, how many animals of each type are there ?, is: a) C + P = 18 B) 2C + P = 18 C) 2C = 18 D) 2C + P = 19 E) 2C-P = 18 a) 2C + P = 66 b) 2C-P = 18 c) 4C + 2P = 66 d) 4C + 2P = 66 e) 2C + P = 66

Answer 1

Answer:

4C + 2P = 66

2C=18

Step-by-step explanation:

Rabbits have 4 legs and chickens have 2 legs, together they have 66 legs.

There are 18 ears, that belong to rabbits. So equations to find the animals:

4C + 2P = 66

2C=18

Answer regarding number of animals:

Rabbits- 9 and chickens- 15
