Question

Витя загадал число Х. Х>5, Х<У, а У+2<10. Х =?

Answer 1

Из того, что х>5 и у>х, следует, что у>5.
Имеем,
у>5 и 10>у+2
у>5 и у<8.
Откуда, получаем, что у=6 или у =7, а значит, в качестве х Витя загадал число 6.
Ответ : х=6.

Answer 2

To find the value of X, we need to follow the given conditions:

1. X > 5
2. X < У
3. У + 2 < 10

Let's break it down step by step:

Condition 3: У + 2 < 10 Subtract 2 from both sides of the inequality: У < 10 - 2 У < 8

Now, we know that У is less than 8.

Condition 2: X < У Since X is less than У, and we already found that У < 8, we can say: X < 8

Condition 1: X > 5 We know X is greater than 5, so: X > 5

Now we have two inequalities:

1. X > 5
2. X < 8

To find a value of X that satisfies both inequalities, we can pick any number between 6 and 7 (excluding 6 and 7), as those values would satisfy both conditions.

So, X could be any value in the range (6, 7).
