Answer 1

1) 0,8+x+x+2,4x=14
x+x+2,4x=14-0,8
4,4x=13,2
x=13,2÷4,4
x=3 (кг) конфет было во второй коробке.
2) 3+0,8=3,8 (кг) конфет было в первой коробке.
3) 3×2,4=7,2 (кг) конфет было в третьей коробке.

Answer 2

Problem Analysis

We are given three boxes of candies, and the total weight of all the candies is 14 kg. The first box weighs 0.8 kg more than the second box, and the third box weighs 2.4 times more than the second box. We need to find the number of candies in each box.

Solution

Let's assume the weight of the second box is x kg.

According to the problem, the first box weighs 0.8 kg more than the second box, so the weight of the first box is x + 0.8 kg.

The third box weighs 2.4 times more than the second box, so the weight of the third box is 2.4x kg.

The sum of the weights of all three boxes is 14 kg, so we can write the equation:

x + (x + 0.8) + 2.4x = 14

Simplifying the equation:

4.4x + 0.8 = 14

Subtracting 0.8 from both sides:

4.4x = 13.2

Dividing both sides by 4.4:

x = 3

Now that we have the weight of the second box, we can find the weights of the other two boxes:

- The weight of the first box is x + 0.8 = 3 + 0.8 = 3.8 kg. - The weight of the third box is 2.4x = 2.4 * 3 = 7.2 kg.

Therefore, the weights of the three boxes are: - First box: 3.8 kg - Second box: 3 kg - Third box: 7.2 kg

Answer

The first box contains 3.8 kg of candies, the second box contains 3 kg of candies, and the third box contains 7.2 kg of candies.
