Question

Задумай двузначное число и увеличь его на 7. Результат отнимиот 110 и прибавь 15 .. К значению суммы прибавь задуманное число результат раздели пополам. От значения частного отними 9 и результат умнож на 3. У тебя получилось 150? Как изменить условие фокуса,чтобы можно было задумывать любое трёхзначное число?

Answer 1

Задумала число: 10. 10+7=17,110-17=93,93+15=108,108+10=118,118:2=59,59-9=50,50*3=150.

Answer 2

Задумай трехзначное число и увеличь его на 70. Результат отними от 1100 и прибавь 150 .. К значению суммы прибавь задуманное число результат раздели на 20.От значения частного отними 9 и результат умнож на 3. У тебя получилось 150?

Answer 3

Solving the Equation

To solve the given equation, let's first break down the steps and solve it step by step.

1. Choose a Two-Digit Number - Let's choose the two-digit number as xy.

2. Increase the Number by 7 - The result of increasing the number by 7 is xy + 7.

3. Subtract 110 and Add 15 - After subtracting 110 and adding 15, the result is xy + 7 - 110 + 15.

4. Add the Chosen Number - Adding the chosen number to the previous result gives us xy + 7 - 110 + 15 + xy.

5. Divide the Sum by 2 - Dividing the sum by 2 yields (xy + 7 - 110 + 15 + xy) / 2.

6. Subtract 9 and Multiply by 3 - Subtracting 9 and multiplying by 3 gives us 3 * ((xy + 7 - 110 + 15 + xy) / 2 - 9).

7. Check if the Result is 150 - Now, we need to check if the result obtained from the previous step is 150.

Solving the Equation for Any Three-Digit Number

To modify the focus of the equation to allow for any three-digit number, we can simply adjust the initial steps to accommodate a three-digit number.

1. Choose a Three-Digit Number - Let's choose the three-digit number as xyz.

2. Increase the Number by 7 - The result of increasing the number by 7 is xyz + 7.

3. Subtract 110 and Add 15 - After subtracting 110 and adding 15, the result is xyz + 7 - 110 + 15.

4. Add the Chosen Number - Adding the chosen number to the previous result gives us xyz + 7 - 110 + 15 + xyz.

5. Divide the Sum by 2 - Dividing the sum by 2 yields (xyz + 7 - 110 + 15 + xyz) / 2.

6. Subtract 9 and Multiply by 3 - Subtracting 9 and multiplying by 3 gives us 3 * ((xyz + 7 - 110 + 15 + xyz) / 2 - 9).

By following these steps, the equation can be modified to accommodate any three-digit number.
