Question

Бригада рабочих за 2 недели изготовила 357 деталей, причём за вторую неделю было изготовлено на 85 деталей больше. Сколько деталей было изготовлено за вторую неделю?

Answer 1

Ответ:

357 - общее количество деталей

х - количество деталей за 1 неделю

х+85 - количество деталей за 2 неделю

х+х+85=357 - всего деталей за 2 недели

2х=357-85

2х=272

х=136 - за 1 неделю

136+85=221 - за 2 неделю

Answer 2

Calculation of the Number of Parts Manufactured in the Second Week

To calculate the number of parts manufactured in the second week, we need to determine the number of parts manufactured in the first week and the additional number of parts manufactured in the second week.

Let's assume that the number of parts manufactured in the first week is represented by x.

According to the given information, the total number of parts manufactured in two weeks is 357, and the number of parts manufactured in the second week is 85 more than the number manufactured in the first week.

So, we can set up the following equation:

x + (x + 85) = 357

Simplifying the equation:

2x + 85 = 357

Subtracting 85 from both sides:

2x = 272

Dividing both sides by 2:

x = 136

Therefore, the number of parts manufactured in the first week is 136.

To find the number of parts manufactured in the second week, we can substitute the value of x into the equation:

x + 85 = 136 + 85 = 221

Therefore, the number of parts manufactured in the second week is 221.

Answer:

The number of parts manufactured in the second week is 221.
