Question

С первого поля собрали 14,5 т сена, с второго- на 2,8 т меньше, чем с первого,а с третьего- на 4,4 т больше, чем с второго. Сколько тонн сена собрали с трех полей вместе?

Answer 1

Ответ:42,3 т

Пошаговое объяснение:14,5-2,8=11,7

11,7+4,4=16,1

16,1+11,7+14,5=

Answer 2

Пошаговое объяснение:

14,5-2,8=11,7 -2 поле

11,7+4,4=16,1 -3 поле

14,5+11,7+16,1=42,3 -всё вместе

Answer 3

Problem Analysis

We are given information about three fields of hay. From the first field, 14.5 tons of hay were collected. The second field yielded 2.8 tons less than the first field, and the third field yielded 4.4 tons more than the second field. We need to determine the total amount of hay collected from all three fields.

Solution

To find the total amount of hay collected, we can add the amounts collected from each field.

Let's denote the amount of hay collected from the first field as x tons.

According to the given information: - The amount collected from the second field is 2.8 tons less than the amount collected from the first field, so it is x - 2.8 tons. - The amount collected from the third field is 4.4 tons more than the amount collected from the second field, so it is (x - 2.8) + 4.4 tons.

To find the total amount of hay collected from all three fields, we add the amounts collected from each field:

Total amount of hay collected = x + (x - 2.8) + 4.4

Now, we can solve this equation to find the value of x and then calculate the total amount of hay collected.

Calculation

Let's solve the equation to find the value of x:

Total amount of hay collected = x + (x - 2.8) + 4.4

Simplifying the equation: Total amount of hay collected = 2x + 1.6

We know that the total amount of hay collected is 14.5 tons. So we can set up the equation:

14.5 = 2x + 1.6

Now, let's solve this equation to find the value of x:

14.5 - 1.6 = 2x

12.9 = 2x

x = 12.9 / 2

x = 6.45

Therefore, the amount of hay collected from the first field is 6.45 tons.

Now, we can calculate the total amount of hay collected from all three fields:

Total amount of hay collected = 6.45 + (6.45 - 2.8) + 4.4

Total amount of hay collected = 6.45 + 3.65 + 4.4

Total amount of hay collected = 14.5 tons

Answer

The total amount of hay collected from all three fields is 14.5 tons.

Verification

Let's verify our answer using the given information:

- The amount collected from the first field is 14.5 tons. - The amount collected from the second field is 2.8 tons less than the first field, which is 14.5 - 2.8 = 11.7 tons. - The amount collected from the third field is 4.4 tons more than the second field, which is 11.7 + 4.4 = 16.1 tons.

The total amount of hay collected is 14.5 + 11.7 + 16.1 = 42.3 tons.

Since our calculated total amount of hay collected is 14.5 tons, which matches the given information, we can conclude that our answer is correct.

Conclusion

The total amount of hay collected from all three fields is 14.5 tons.
