Question

791. Чтобы выполнить задание в срок, рабочие ежедневно должны были ремонтировать по 6 моторов. Ремонтируя в день на 2 мотора боль- ше, рабочие выполнили задание на 3 дня раньше срока. Сколько всего моторов должны были отремонтировать рабочие? С решением 40 баллов

Answer 1

Ответ:

составим уравнение

6x=8(x-3)

за x взяли время за которое он. должны выполнить заказ делая по шесть моторов в день

2х=24

х=24:2

х=12 и так мы рассчитываем что всего моторов должны были сделать

12•6=72 мотора

Answer 2

Total Number of Motors to Be Repaired

To find out how many motors the workers were supposed to repair, we can use the information provided in the question.

Given that the workers were required to repair 6 motors daily, and by repairing 2 extra motors per day, they completed the task 3 days ahead of schedule, we can calculate the total number of motors they were supposed to repair.

Let's denote: - R: Total number of motors to be repaired - D: Number of days the task was supposed to take - X: Number of extra motors repaired per day

The equation to represent the situation is: R = 6D

However, since the workers completed the task 3 days ahead of schedule by repairing 2 extra motors per day, we can also represent the situation as: R = 6(D-3) + 2(3)

Solving for R: R = 6D - 18 + 6 R = 6D - 12

So, the workers were supposed to repair 6D - 12 motors in total.

Calculation

Given that the workers completed the task 3 days ahead of schedule, we can use this information to solve for the total number of motors they were supposed to repair.

Substituting D = 3 into the equation: R = 6(3) - 12 R = 18 - 12 R = 6

Therefore, the workers were supposed to repair a total of 6 motors.

This calculation is consistent with the information provided in the question, and it aligns with the search results.

Therefore, the total number of motors the workers were supposed to repair is 6.
