Question

Задача. 15 баллов. а) Длина тюленя в 11 раз меньше, чем длина синего кита. Синий кит на 30 м ллиннее тюленя.Чему равна длина каждого из этих животных?

Answer 1

11*х -х=30
10х=30
х=30:10=3
тюлень 3 метра,синий кит 33м

Answer 2

Problem Statement

Длина тюленя в 11 раз меньше, чем длина синего кита. Синий кит на 30 метров длиннее тюленя. Чему равна длина каждого из этих животных?

Solution

To solve this problem, let's assign variables to the lengths of the seal and the blue whale. Let's call the length of the seal "x" and the length of the blue whale "y".

According to the problem statement, the length of the seal is 11 times smaller than the length of the blue whale. Mathematically, we can express this as:

x = y/11

Additionally, the problem states that the blue whale is 30 meters longer than the seal. Mathematically, we can express this as:

y = x + 30

Now, we can solve this system of equations to find the values of x and y.

Substituting the first equation into the second equation, we get:

y = (y/11) + 30

To solve for y, we can multiply both sides of the equation by 11:

11y = y + 330

Simplifying the equation, we get:

10y = 330

Dividing both sides of the equation by 10, we find:

y = 33

Now that we have the value of y, we can substitute it back into the first equation to find the value of x:

x = 33/11

Simplifying the equation, we get:

x = 3

Therefore, the length of the seal is 3 meters and the length of the blue whale is 33 meters.

Answer

The length of the seal is 3 meters and the length of the blue whale is 33 meters.
