Question

Решите!!!осенью с 3 полей собрали и увезли 250 мешков картофеля.С 1 поля собрали на 40 мешков меньше чем со 2,но на 20 больше,чем с 3.Сколько мешков картофеля собрали со 2 поля

Answer 1

Пусть х=собрали с 1 поля,значит со 2=х-40,а с 3=х+20.
х+х-40+х+20=250
х+х-40+х=250-20=230
3х-40=230
3х=230+40=270
х=270÷3=90;значит с 1 поля собрали 90 мешков.
90-40=50 (м.)
Ответ:50 мешков

Answer 2

Problem Analysis

We are given the information that in the fall, 250 sacks of potatoes were harvested and transported from three fields. From the first field, they harvested 40 sacks less than from the second field, but 20 sacks more than from the third field. We need to determine how many sacks of potatoes were harvested from the second field.

Solution

Let's assume that the number of sacks harvested from the second field is x.

From the information given, we can set up the following equations:

1. The total number of sacks harvested from all three fields is 250: - x + (x - 40) + (x + 20) = 250

2. Simplifying the equation: - 3x - 20 = 250

3. Solving for x: - 3x = 270 - x = 90

Therefore, 90 sacks of potatoes were harvested from the second field.

Answer

The number of sacks of potatoes harvested from the second field is 90.
