Question

Купили два куска ткани по одинаковой цене. В одном было 4 м ткани, а в другом - 5 м такой же ткани. За всю покупку заплатили 2115 тенге . Сколько стоит каждый кусок ткани?Помогите пожалуйста

Answer 1

Всю сумму делим на общее количество метров 2115/9=235 тенге за метр.
далее умножаем на метраж каждого куска
235*4=940 тенге стоимость 1го куска ткани.
235*5=1175 тенге стоимость 2го куска.

Problem Analysis

We have two pieces of fabric, one measuring 4 meters and the other measuring 5 meters. The total cost of both pieces is 2115 tenge. We need to determine the cost of each piece of fabric.

Solution

Let's assume the cost of each meter of fabric is x tenge.

The cost of the first piece of fabric (4 meters) would be 4x tenge. The cost of the second piece of fabric (5 meters) would be 5x tenge.

According to the problem, the total cost of both pieces is 2115 tenge. Therefore, we can write the equation:

4x + 5x = 2115

Simplifying the equation:

9x = 2115

To find the value of x, we divide both sides of the equation by 9:

x = 2115 / 9

Now, let's calculate the value of x:

x = 235

Therefore, each meter of fabric costs 235 tenge.

Answer

Each piece of fabric costs 235 tenge.
