149 хамдам задумал число если к нему прибавить 45 и к полученой сумме прибавить ещё 32 то получится 84.какое число задумал хамдам? и ещё 150 в коробку со спичками положили 647 спичек после чего их стало 1.121 штуки сколько спичек было в коробке первоначально номер 151 после того как из бочки отлили 214 л воды в ней осталось 391 л сколько воды было в бочке первоначальноПОЖАЛУЙСТА НОРМАЛЬНЫЕ ЛЮДИ ОТЗОВИТЕСЬ И ВСЕ ПОЖАЛУЙСТА РЕШИТЕ УМОЛЯЮ кстати это все уровнения задачи ​

Answer 1

Ответ:

Пошаговое объяснение:

№149

Пусть Хамдам задумал число - х

х + 45 + 32 = 84

х = 84 - 45 - 32

х = 7

№150

х + 647 = 1121

х = 1121 - 647

х = 474 спички было в коробке первоначально

№151

х - 214 = 391

х = 391 + 214

х = 605 л воды было в бочке первоначально

Answer 2

Ответ:

Пошаговое объяснение:

№149

Задуманное число = х

(х + 45) + 32 = 84

х + 45 + 32 = 84

х + 77 = 84

х = 84 - 77

х = 7

Задуманное число = (х) = 7

№ 150

Было спичек первоначально = х

х + 647 = 1121

х = 1121 - 647

х = 474

Было спичек первоначально = (х) = 474 спички

№ 151

Было в бочке первоначально = х л

х - 214 = 391

х = 391 + 214

х = 605

Было в бочке первоначально = (х) = 605 л

Answer 3

Hamdam's Number

To find the number that Hamdam had in mind, we can follow the given steps:

1. Hamdam thought of a number. 2. He added 45 to that number. 3. He added 32 to the sum of the previous step. 4. The final result was 84.

Let's solve this step by step:

Let's assume the number Hamdam had in mind is x.

According to the given information, we can set up the equation:

x + 45 + 32 = 84

To find the value of x, we can simplify the equation:

x + 77 = 84

Subtracting 77 from both sides of the equation, we get:

x = 84 - 77

Simplifying further, we find:

x = 7

Therefore, the number that Hamdam had in mind is 7.

Number of Matches in the Box

In the second problem, we are given the following information:

1. Initially, there were 150 matches in the box. 2. After some time, the number of matches increased to 1,121.

We need to find the number of matches that were initially in the box.

Let's solve this step by step:

Let's assume the number of matches initially in the box is x.

According to the given information, we can set up the equation:

x + 647 = 1,121

To find the value of x, we can simplify the equation:

x = 1,121 - 647

Simplifying further, we find:

x = 474

Therefore, the number of matches initially in the box was 474.

Amount of Water in the Barrel

In the third problem, we are given the following information:

1. Initially, there was a certain amount of water in the barrel. 2. 214 liters of water were poured out of the barrel. 3. After pouring out the water, there were 391 liters of water left in the barrel.

We need to find the amount of water that was initially in the barrel.

Let's solve this step by step:

Let's assume the amount of water initially in the barrel is x liters.

According to the given information, we can set up the equation:

x - 214 = 391

To find the value of x, we can simplify the equation:

x = 391 + 214

Simplifying further, we find:

x = 605

Therefore, the amount of water initially in the barrel was 605 liters.

I hope this helps! Let me know if you have any further questions.
