Answer 1

1)пусть х м.собрали со второго поля ,с 1 п.-(х-40), со 2п.-х,с 3 п.-(х+20). х-40+х+х+20=250. 3х=250+20. 3х=270. х= 90. проверка: 50+90+110=250,задача решена верно.

Answer 2

Problem Analysis

We are given that a total of 250 sacks of potatoes were collected and transported from three fields in the fall. The number of sacks collected from the first field is 40 less than the number collected from the second field, but 20 more than the number collected from the third field. We need to determine how many sacks were collected from the second field.

Solution

Let's assume that the number of sacks collected from the third field is x.

According to the given information: - The number of sacks collected from the first field is 40 less than the number collected from the second field. Therefore, the number of sacks collected from the first field is (x + 40). - The number of sacks collected from the first field is 20 more than the number collected from the third field. Therefore, the number of sacks collected from the first field is (x + 20).

To find the total number of sacks collected, we can add up the number of sacks collected from each field: (x + (x + 40) + (x + 20)) = 250.

Simplifying the equation: 3x + 60 = 250, 3x = 190, x = 190/3, x ≈ 63.33.

Therefore, approximately 63.33 sacks were collected from the third field.

To find the number of sacks collected from the second field, we can substitute the value of x into the equation (x + 40): 63.33 + 40 ≈ 103.33.

Therefore, approximately 103.33 sacks were collected from the second field.

Answer

Approximately 103.33 sacks were collected from the second field.
