Question

Миша загадал число, увеличил его на этого числа и получил 216. Арсений загадал своё любимое 11 2 число, прибавил к нему этого числа и получил 15. Олеся тоже загадала произвольное число, 3 2 уменьшила его на этого числа и получила 42. Какие числа задумали ребята? 9 Запиши в поле ответа верное число. Миша задумал число Арсений задумал число Олеся задумала число​

Answer 1

Миша задумал: 108

Арсений задумал: 1.2

Олеся задумала: 28

Миша:

216 / 2 = 108

Арсений:

2/11 = 15

11 - 2 = 9

9 частей числа прибавили к числу.

9/15=0.6 это 1 часть

0.6 ×2(так как всего 2 части)=1.2

Олеся:

3/2 = 42

3 - 2 = 1 часть этого числа прибавили

42 / 3 = 14 это 1 часть

14 + 14 = 28

Answer 2

Problem Analysis

We are given three scenarios where three different people, Misha, Arseniy, and Olesya, have each chosen a number and performed some operations on it. We need to determine the numbers they chose.

Solution

Let's analyze each scenario step by step:

1. Misha: - Misha chose a number and increased it by that number, resulting in 216. - Let's assume the number Misha chose is x. - The equation can be written as: x + x = 216. - Simplifying the equation, we get: 2x = 216. - Solving for x, we find: x = 108.

2. Arseniy: - Arseniy chose his favorite number, added another number to it, and obtained 15. - Let's assume Arseniy's favorite number is y. - The equation can be written as: y + y + 2 = 15. - Simplifying the equation, we get: 2y + 2 = 15. - Solving for y, we find: y = 6.5.

3. Olesya: - Olesya chose a random number, decreased it by another number, and obtained 42. - Let's assume Olesya's chosen number is z. - The equation can be written as: z - z - 2 = 42. - Simplifying the equation, we get: -2 = 42. - This equation has no solution, which means there is an error in the given information. It is not possible to obtain a negative number by subtracting a number from itself.

Conclusion

Based on the given information, we can determine the numbers chosen by Misha and Arseniy, but there seems to be an error in the information provided for Olesya. The numbers are as follows: - Misha chose the number 108. - Arseniy chose the number 6.5. - Olesya's number cannot be determined due to an error in the information provided.

Answer 3

Problem Analysis

We are given three scenarios where three different individuals, Misha, Arseniy, and Olesya, have each chosen a number and performed some operations on it. We need to determine the numbers they have chosen based on the given information.

Solution

Let's analyze each scenario separately and solve for the unknown numbers.

Scenario 1: Misha Misha chose a number, increased it by that number, and obtained 216. Let's represent the unknown number as 'x'. According to the given information, we can set up the following equation:

x + x = 216

Simplifying the equation, we have:

2x = 216

To solve for 'x', we divide both sides of the equation by 2:

x = 216 / 2

Calculating the result:

x = 108

Therefore, Misha's chosen number is 108.

Scenario 2: Arseniy Arseniy chose his favorite number, added another number to it, and obtained 15. Let's represent Arseniy's favorite number as 'y' and the unknown number as 'z'. According to the given information, we can set up the following equation:

y + z = 15

We are also given that Arseniy's favorite number is 112. Substituting this value into the equation, we have:

112 + z = 15

To solve for 'z', we subtract 112 from both sides of the equation:

z = 15 - 112

Calculating the result:

z = -97

Therefore, the number Arseniy chose is -97.

Scenario 3: Olesya Olesya chose a random number, decreased it by another number, and obtained 42. Let's represent Olesya's chosen number as 'a' and the unknown number as 'b'. According to the given information, we can set up the following equation:

a - b = 42

We are also given that Olesya's chosen number is 32. Substituting this value into the equation, we have:

32 - b = 42

To solve for 'b', we subtract 32 from both sides of the equation:

b = 42 - 32

Calculating the result:

b = 10

Therefore, the number Olesya chose is 10.

Final Answer

Based on the given information, the numbers chosen by the three individuals are as follows: - Misha chose the number 108. - Arseniy chose the number -97. - Olesya chose the number 10.
