Question

Для кормления 3 волков и 2 тигров зоопарк закупает 13 кг мяса ежедневно. В прошлом году тот же зоопарк закупал каждый день 9 кг мяса для 4 волков и одного тигра. Сколько кг мяса съедает за день тигр?

Answer 1

Если 4 волка и 1 тигр съедают 9 кг мяса, значит 8 волков и 2 тигра съедают 9*2 = 18 кг.
18 - 13 = 5 кг мяса съедает 5 волков, так как при вычитании 8 волков и двух тигров и 3 волков и 2 тигров - тигры сокращаются.
5 : 5 = 1 кг мяса съедает 1 волк
9-4 = 5 кг мяса съедает 1 тигр
Проверка 3 * 1 + 2* 5 = 13. 

Answer 2

Calculating the Daily Meat Consumption for a Tiger

To calculate the daily meat consumption for a tiger, we can use the given information about the total meat purchased for the wolves and tigers in the zoo.

Given: - Wolves: 3 wolves - Tigers: 2 tigers - Total meat purchased daily: 13 kg

In the previous year: - Wolves: 4 wolves - Tigers: 1 tiger - Total meat purchased daily: 9 kg

Let's calculate the daily meat consumption for a tiger.

Solution:

To find out how much meat a tiger eats in a day, we can use a system of equations based on the given information.

Let's assume: - x: the amount of meat consumed by a tiger in a day (in kg) - y: the amount of meat consumed by a wolf in a day (in kg)

We can set up the following system of equations based on the given information: 1. For the current year: - 3x + 3y = 13 (total meat for 3 wolves and 2 tigers) 2. For the previous year: - 4x + y = 9 (total meat for 4 wolves and 1 tiger)

We can solve this system of equations to find the value of x, which represents the daily meat consumption for a tiger.

Solving the System of Equations:

Using the system of equations, we can solve for the value of x:

1. Multiply the second equation by 3 to make the coefficients of y in both equations equal: - 12x + 3y = 27

2. Subtract the modified second equation from the first equation: - (3x + 3y) - (12x + 3y) = 13 - 27 - -9x = -14 - x = 14 / 9 - x ≈ 1.56 kg

Answer:

The tiger eats approximately 1.56 kg of meat per day.
