Question

В числе А запятую перенесли вправо на один знак и получили число В, а затем ещё один знак вправо и получилось число С. Чему равно А, если С + В - А = 176 кто ответит награда 34 балла

Answer 1

Решение.
1)А=А – первое число
2) В= 10А – второе
3) С= 100А – третье
4)110 А – А = 109А
Составляем уравнение:
5) 109 А= 13.08
6) А= 13.08 :109
7) А=0.12
Ответ: 0.12

Answer 2

Problem Analysis

We are given three numbers, A, B, and C, with the following conditions: 1. A, when shifted one digit to the right, becomes B. 2. B, when shifted one digit to the right, becomes C. 3. C - B = A + 176.

We need to find the value of A.

Solution

Let's break down the problem step by step:

1. A, when shifted one digit to the right, becomes B. - This means that B is obtained by moving the rightmost digit of A to the leftmost position. - For example, if A = 123, then B = 312.

2. B, when shifted one digit to the right, becomes C. - This means that C is obtained by moving the rightmost digit of B to the leftmost position. - For example, if B = 312, then C = 231.

3. C - B = A + 176. - We are given that the difference between C and B is equal to A plus 176. - Mathematically, this can be represented as C - B = A + 176.

To find the value of A, we can use the information from steps 1 and 2.

Let's assume that A is a three-digit number with digits a, b, and c. Then, we can represent A as 100a + 10b + c.

Using the information from step 1, we can write B as 100c + 10a + b.

Using the information from step 2, we can write C as 100b + 10c + a.

Substituting these values into the equation C - B = A + 176, we get:

(100b + 10c + a) - (100c + 10a + b) = (100a + 10b + c) + 176.

Simplifying the equation, we get:

99b - 99c + 99a = 176.

Dividing both sides of the equation by 99, we get:

b - c + a = 2.

Since a, b, and c are digits, the only possible values that satisfy this equation are a = 1, b = 2, and c = 1.

Therefore, A = 100a + 10b + c = 100 + 20 + 1 = 121.

Hence, the value of A is 121.

Answer

The value of A is 121.

Note: The answer is based on the given information and the assumption that A is a three-digit number.
