Question

Из 19 м ткани сшили 6 рубашек и 5 платьев. Для пошива 2 рубашек требуется на 1 м материи больше, чем для пошива 1-го платья. Сколько метров материи нужно для пошива 1 рубашки и платья? О РЕШИТЕЕ ПОЖАЛУЙСТА, НУЖНО РЕШИТЬ ЭТУ ЗАДАЧУ СПОСОБОМ ПОСТАНОВКИ, ПОМОГИТЕ ЗАВТРА ТЕТРАДЬ СДАВАТЬ()

Answer 1

Для пошива платья- x материи, а для пошива одной рубашки (x+1)/2 для шести рубашек: ((x+1)/2)*6, для 5 платьев: x*5
уравнение: ((Х+1)/2)*6+Х*5=19

Answer 2

Calculation of Fabric Required for 1 Shirt and 1 Dress

To calculate the amount of fabric required for 1 shirt and 1 dress, we need to consider the given information:

- 19 meters of fabric were used to make 6 shirts and 5 dresses. - It takes 1 meter more fabric to make 2 shirts than to make 1 dress.

Let's break down the problem step by step:

1. Calculate the fabric required for 1 shirt: - Let's assume the fabric required for 1 dress is "x" meters. - Since it takes 1 meter more fabric to make 2 shirts than to make 1 dress, the fabric required for 2 shirts would be "x + 1" meters. - Therefore, the fabric required for 1 shirt would be "(x + 1) / 2" meters.

2. Calculate the fabric required for 1 dress: - We know that 19 meters of fabric were used to make 6 shirts and 5 dresses. - So, the fabric used for 6 shirts would be "(6 * (x + 1) / 2)" meters. - And the fabric used for 5 dresses would be "5 * x" meters. - Therefore, the total fabric used would be "(6 * (x + 1) / 2) + (5 * x)" meters.

Now, we can set up an equation to solve for "x":

`(6 * (x + 1) / 2) + (5 * x) = 19`

Let's solve this equation to find the value of "x" and then calculate the fabric required for 1 shirt and 1 dress.

Solution:

To solve the equation `(6 * (x + 1) / 2) + (5 * x) = 19`, we can simplify it as follows:

`(3 * (x + 1)) + (5 * x) = 19`

Simplifying further:

`3x + 3 + 5x = 19`

Combining like terms:

`8x + 3 = 19`

Subtracting 3 from both sides:

`8x = 16`

Dividing both sides by 8:

`x = 2`

Now that we have found the value of "x" to be 2, we can calculate the fabric required for 1 shirt and 1 dress:

- Fabric required for 1 shirt: `(x + 1) / 2 = (2 + 1) / 2 = 3 / 2 = 1.5 meters` - Fabric required for 1 dress: `x = 2 meters`

Therefore, to make 1 shirt and 1 dress, you would need 1.5 meters of fabric for the shirt and 2 meters of fabric for the dress.

Please note that the solution provided is based on the given information and the assumption made.
