Question

Определи массу лисы белочки и обезьянки,если известно; масса зайца - 3 кг: масса двух одинаковых зайцев на 1 кг меньше массы лисы;масса двух обезьян равна массе одного зайца и одной лисы; масса обезьяны на 1 кг больше массы одного зайца и одной белки.

Answer 1

Лиса: 3+3+1=7 кг
обезьяна: 2х=3+7
                х=10/2=5кг
белка: 5+1=3+х
           6-3=х
           х=3

Answer 2

3+3+1=7 кг масса лисы
(3+7):2=5кг масса обезьяны
5+1-3=3кг масса белки

Answer 3

Problem Analysis

We are given the following information: - The mass of a rabbit is 3 kg. - The mass of two identical rabbits is 1 kg less than the mass of a fox. - The mass of two monkeys is equal to the mass of one rabbit and one fox. - The mass of a monkey is 1 kg more than the mass of one rabbit and one squirrel.

We need to determine the masses of the fox, squirrel, and monkey.

Solution

Let's assign variables to the unknown masses: - Mass of the fox = F - Mass of the squirrel = S - Mass of the monkey = M

From the given information, we can write the following equations:

1. The mass of two identical rabbits is 1 kg less than the mass of a fox: 2 * 3 kg = F - 1 kg Simplifying, we get: F = 6 kg + 1 kg = 7 kg

2. The mass of two monkeys is equal to the mass of one rabbit and one fox: 2M = 3 kg + 7 kg Simplifying, we get: M = 10 kg / 2 = 5 kg

3. The mass of a monkey is 1 kg more than the mass of one rabbit and one squirrel: M = 3 kg + S + 1 kg Simplifying, we get: S = M - 4 kg = 5 kg - 4 kg = 1 kg

Therefore, the masses of the animals are: - Fox: 7 kg - Squirrel: 1 kg - Monkey: 5 kg

Answer

The mass of the fox is 7 kg, the mass of the squirrel is 1 kg, and the mass of the monkey is 5 kg.
