Question

После того,как температура упала на 2 градуса она ещё упала на 2 градуса.Потом она поднялась на 4 градуса и опять упала на 3 градуса.Показатель термометр стал -1 градус.Сколько градусов показывал термометр вначале?

Answer 1

Как мне кажжеться ответ будет верен : -2 + (-2)=-4+4=0 -3 =-3
я так считаю

Answer 2

Х-2-2+4-3=-1
ответ х=2 

Answer 3

Calculation of Initial Temperature

To calculate the initial temperature, we need to analyze the given information step by step.

1. The temperature initially dropped by 2 degrees. 2. Then it dropped by another 2 degrees. 3. After that, it increased by 4 degrees. 4. Finally, it dropped by 3 degrees and reached -1 degree.

Let's calculate the initial temperature using these steps:

1. The temperature initially dropped by 2 degrees, so the temperature before this drop was 2 degrees higher than the current temperature of -1 degree. 2. Then it dropped by another 2 degrees, so the temperature before this second drop was 2 degrees higher than the temperature before the first drop. 3. After that, it increased by 4 degrees, so the temperature before this increase was 4 degrees lower than the temperature before the second drop. 4. Finally, it dropped by 3 degrees and reached -1 degree, so the temperature before this drop was 3 degrees higher than the current temperature of -1 degree.

To summarize:

- The temperature initially dropped by 2 degrees. - Then it dropped by another 2 degrees. - After that, it increased by 4 degrees. - Finally, it dropped by 3 degrees and reached -1 degree.

Based on this information, we can calculate the initial temperature as follows:

- The temperature before the first drop was 2 degrees higher than -1 degree, so it was 1 degree. - The temperature before the second drop was 2 degrees higher than 1 degree, so it was 3 degrees. - The temperature before the increase was 4 degrees lower than 3 degrees, so it was -1 degree.

Therefore, the initial temperature was -1 degree.
