Question

Купили три отреза одинаковой ткани. В первом отрезе 7 и ткани, во втором в два раза больше, чем во втором. За все три отреза заплатили 4320 руб. Сколько стоит каждый отрез

Answer 1

1) 7*2=14 (м) во 2 отрезе
2) считаем, сколько метров в 3 отрезе
3) 7+14+метры 3 отреза=общее кол-во метров ткани
4) 4320: общее кол-во метров ткани=сколько стоит 1 м ткани
5) стоимость 1 м*7=стоимость 1 отреза
6) стоимость 1 м* 14=стоимость 2 отреза
7) стоимость 1 м*кол-во ткани в 3 отрезе=стоимость 3 отреза

конкретнее никак без информации о метраже 3 отреза

Answer 2

Calculating the Cost of Each Fabric Piece

To calculate the cost of each fabric piece, we can use a system of equations based on the given information.

Let's denote the cost of the first fabric piece as x. According to the given information: - The first fabric piece costs x rubles. - The second fabric piece costs 2x rubles (twice the cost of the first fabric piece). - The third fabric piece costs 7x rubles (seven times the cost of the first fabric piece).

We also know that the total cost for all three fabric pieces is 4320 rubles.

Setting Up the Equation

We can set up the equation based on the information above: x + 2x + 7x = 4320

Solving for x

Solving the equation: 10x = 4320 x = 432

Calculating the Cost of Each Fabric Piece

Now that we have the value of x, we can calculate the cost of each fabric piece: - The first fabric piece costs 432 rubles. - The second fabric piece costs 2 * 432 = 864 rubles. - The third fabric piece costs 7 * 432 = 3024 rubles.

So, each fabric piece costs 432, 864, and 3024 rubles respectively.
