Question

Заяц на 3 кг тяжелее кролика. 2 зайца весят столько же, сколько 5 кроликов. какова масса зайца и кролика отдельно?

Answer 1

(х+3)*2=5х    2х+6=5х    6=5х-2х   6=3х  2=х    Выразим вес кролика через х ,и тогда мое уравнение станет понятным,Ответ:кролик весит 2 кг,а заяц 5 кг

Answer 2

Calculating the Mass of the Hare and the Rabbit

To solve this problem, we can use a system of equations to represent the given information and solve for the masses of the hare and the rabbit separately.

Let's denote: - x as the mass of the hare (in kg) - y as the mass of the rabbit (in kg)

We are given the following information: 1. The hare is 3 kg heavier than the rabbit. 2. Two hares weigh the same as 5 rabbits.

We can represent this information in the form of equations:

1. x = y + 3 (The hare is 3 kg heavier than the rabbit) 2. 2x = 5y (Two hares weigh the same as 5 rabbits)

Now, we can solve these equations to find the masses of the hare and the rabbit.

Solving the Equations

Using the first equation, we can express x in terms of y: x = y + 3

Substitute this expression for x into the second equation: 2(y + 3) = 5y

Expanding and solving for y: 2y + 6 = 5y 6 = 5y - 2y 6 = 3y y = 2

Now that we have found the mass of the rabbit (y = 2 kg), we can find the mass of the hare using the first equation: x = 2 + 3 x = 5

Answer

So, the mass of the hare is 5 kg and the mass of the rabbit is 2 kg.
