Question

По двору гуляли цыплята и котята вместе у них 14 голов и 38 ног сколько котят и сколько цыплят гуляло по двору. ( подскажите пожалуста с решением по действием.)

Answer 1

Если котят х, то цыплят = 14-х.
Лап у котёнка 4, т.е кошачьих лап во дворе = 4*х
Значит. цыплячьих лап = (38-4*х), а самих цыплят = (38-4*х)/2
14-х = (38-4х)/2
14-х = 19-2х
х=19-14
х=5
Котят — 5, а цыплят = 5+4 = 9

Answer 2

Problem Analysis

We are given that there were chickens and kittens playing together in a yard. The total number of heads is 14, and the total number of legs is 38. We need to determine how many kittens and how many chickens were playing in the yard.

Solution

Let's assume the number of kittens is represented by k and the number of chickens is represented by c.

We can use the following information to set up two equations:

1. The total number of heads: k + c = 14. 2. The total number of legs: 4k + 2c = 38.

We can solve this system of equations to find the values of k and c.

Solving the System of Equations

To solve the system of equations, we can use the method of substitution or elimination. Let's use the method of substitution.

From equation 1, we can express c in terms of k: c = 14 - k.

Substituting this value of c into equation 2, we get: 4k + 2(14 - k) = 38.

Simplifying the equation: 4k + 28 - 2k = 38, 2k + 28 = 38, 2k = 38 - 28, 2k = 10, k = 10 / 2, k = 5.

Now that we have the value of k, we can substitute it back into equation 1 to find the value of c: c = 14 - k, c = 14 - 5, c = 9.

Therefore, there were 5 kittens and 9 chickens playing in the yard.

Answer

There were 5 kittens and 9 chickens playing in the yard.

Verification

Let's verify our answer using the given information.

The total number of heads is 5 + 9 = 14, which matches the given information.

The total number of legs is 4(5) + 2(9) = 38, which also matches the given information.

Therefore, our answer is correct.
