Answer 1

петушков - на 25меньше 

курочек-?

цыплят-523

1)523-25=498(ц)

2)498:2=249(ц)

Ответ :249 петушков было выведено в инкубаторе

проверка

249+249=498

498+25=523 

Answer 2

х-петушков

курочек 25+х

х+25+х=523

2х=498

х=249

Ответ 249

Answer 3

Calculating the Number of Roosters

To calculate the number of roosters, we can use the information provided and perform a simple calculation.

Given: - Total number of chicks: 523 - Roosters are 25 less than hens

Let's denote the number of roosters as R and the number of hens as H. We know that the total number of chicks is 523, so we have the equation: R + H = 523 ...(1)

We also know that the number of roosters is 25 less than the number of hens: R = H - 25 ...(2)

We can substitute equation (2) into equation (1) to solve for the number of roosters.

Calculation

Substituting the value of R from equation (2) into equation (1): (H - 25) + H = 523 2H - 25 = 523 2H = 523 + 25 2H = 548 H = 548 / 2 H = 274

Now that we have the number of hens, we can find the number of roosters using equation (2): R = 274 - 25 R = 249

Answer

So, there were 249 roosters hatched in the incubator.
