Animal legs math problem. How many rabbits and turkeys are at the farm. Problem on animals at a farm problem there are rabbits and turkeys at a farm 41 heads and 132 legs in all. 1 that if one third of the animals are chickens then two thirds are pigs and 2 since there are a whole number of chickens there must be three times a whole number of animals.
2 h 4 c 76. That means there are 32 legs. An animal s backbone contains many nerves some of which control the movement of its legs or fins and some of which convey sensations such as hot cold pain.

Each chicken has 2 legs and each cow has 4 legs so. Pretend all the 8 heads are buffalo. Multiply both sides of the first equation by 2 and subtract it from the second equation to get.
Solve for h and c. Before we start though notice. Each animal has 1 head so.
