Question

В мастерскую поступило два куска одинаковой ткани один 105 другой 75 Из всей ткани шили одинаковые шторы Причём из первого куска вышла на 10 штор больше чем со второго Сколько всего штор сшили?

Answer 1

Ответ:

60 штор

Пошаговое объяснение:

105-75=30

30:10=3

105:3=35

75:3=25

35+25=60

Answer 2

Ответ:

105= х + 10

75=х

По пропорции: 75х + 750=105х

750=30х

х=25(штор)

х + 10=35 (штор)

Всего: 25 + 35=60 (штор)

Ответ: 60 штор.

Answer 3

Problem Analysis

We have two pieces of fabric, one measuring 105 units and the other measuring 75 units. From these two pieces, we sewed an equal number of curtains. However, we know that from the first piece, 10 more curtains were made compared to the second piece. We need to determine the total number of curtains that were sewn.

Solution

Let's assume that the number of curtains made from the second piece of fabric is 'x'. Since 10 more curtains were made from the first piece, the number of curtains made from the first piece would be 'x + 10'.

To find the total number of curtains, we need to add the number of curtains made from the first piece and the number of curtains made from the second piece.

So, the equation would be: (x + 10) + x = Total number of curtains

Simplifying the equation, we get: 2x + 10 = Total number of curtains

To solve for 'x', we need to subtract 10 from both sides of the equation: 2x = Total number of curtains - 10

Finally, we divide both sides of the equation by 2 to solve for 'x': x = (Total number of curtains - 10) / 2

Let's calculate the total number of curtains using this formula.

Calculation

Let's denote the total number of curtains as 'C'.

From the equation above, we have: x = (C - 10) / 2

Since the number of curtains made from the second piece is 'x', we also have: x = C - (x + 10)

Simplifying this equation, we get: x = C - x - 10

Combining the two equations, we have: (C - 10) / 2 = C - (C - 10) - 10

Simplifying further, we get: (C - 10) / 2 = C - C + 10 - 10

Simplifying again, we get: (C - 10) / 2 = 0

Multiplying both sides of the equation by 2, we get: C - 10 = 0

Adding 10 to both sides of the equation, we get: C = 10

Therefore, the total number of curtains sewn is 10.

Answer

The total number of curtains sewn is 10.
