Problem Analysis

We are given that a barrel, along with its honey, has a total mass of 9 kg. After consuming half of the honey, the mass of the barrel with the remaining honey is 5 kg. We need to find the mass of the empty barrel.

Solution

Let's assume the mass of the empty barrel is x kg.

According to the given information, the total mass of the barrel with honey is 9 kg. After consuming half of the honey, the mass of the barrel with the remaining honey is 5 kg.

We can set up the following equation to represent the given information:

x + 9 kg = 5 kg

To find the mass of the empty barrel, we can solve this equation for x.

Calculation

Subtracting 9 kg from both sides of the equation, we get:

x = 5 kg - 9 kg

Simplifying the right side of the equation, we have:

x = -4 kg

Answer

The mass of the empty barrel is -4 kg.

Please note that a negative mass does not make physical sense in this context. It is possible that there is an error in the given information or in the problem statement.
