Question

Решите уравнение: 1) x - 2; -17; 2) x-1; -30; 3) x-11-23. х 15 Сколько метров нити в мотке, если израсходовали 2 м и осталось 23 м? ПОМОГИТЕЕЕ СРОЧНООООО ПОЖАЛУЙСТА ​

Answer 1

Ответ:

25 м

Пошаговое объяснение:

23 + 2 = 25 (м) - ниток в мотке

Answer 2

1. x - 2 = -17

To solve the equation, we can isolate x by adding 2 to both sides of the equation:

x - 2 + 2 = -17 + 2

x = -15

Therefore, the solution to the equation x - 2 = -17 is x = -15.

2. x - 1 = -30

Similarly, we can isolate x by adding 1 to both sides:

x - 1 + 1 = -30 + 1

x = -29

So, the solution to the equation x - 1 = -30 is x = -29.

3. x - 11 = -23

To solve for x, we need to isolate x by adding 11 to both sides:

x - 11 + 11 = -23 + 11

x = -12

Therefore, the solution to the equation x - 11 = -23 is x = -12.

Regarding the second question, you mentioned using 2 meters of thread and having 23 meters remaining. To find the total length of the thread, you can add the used length to the remaining length:

Total length of thread = Used length + Remaining length Total length of thread = 2 meters + 23 meters Total length of thread = 25 meters

Therefore, there are 25 meters of thread in the spool.
