I believe it's 75 rabbits. There are 105 animals. There are 75 x 4(rabbit legs) = 300 legs and 30 x 2(chicken legs) = 60 legs, which totals 360 legs. The 75 rabbits plus 30 chickens equals 105 animals.

105 animals in barn chickens and rabbits 360 legs how many of each?
You have to setup two different equations first. One to get the total number of animals and another to get the total number of feet. Since all the chickens plus all the rabbits equals 105 animals, c + r = 105. Since chickens have two feet and rabbits have four feet with the given total as 360, 2c + 4r =360. Then we will define the first equation in terms of "r" by finding the value for "c" in the second equation. 2c + 4r = 360 2c = 360 - 4r c= 180 -2r Now we will substitute this value for "c" into the first equation. c + r = 105 (180 - 2r) + r = 105 180 - r = 105 r = 75 So, there are 75 rabbits. Then to find the number of chickens, we plug in the numerical value for "r" in the first equation. c + r = 105 c + 75 = 105 c = 30 There are 75 rabbits and 30 chickens. This equals 105 animals with a combined total of 360 feet.

There are 40 animals in a farm cows and chickens and the total legs is 100 and the answer is 30 chickens and 10 cows. Use Guess and Check Method. No of Cows No of Chickens Total number of Legs Total number of animals Check 20 × 4 = 80 20 x 2 = 40 120 40 X 15 x 4 = 60 25 x 2 = 50 110 40 X 10 x 4 = 40 30 x 2 = 60 100 40 √ There are 10 cows and 30 chickens in the farm.
