Question

В трёх коробках лежит 63 карандаша причём во второй коробке их в 2 раза больше чем в третьей а в первой в 2 раза меньше чем в третьей сколько карандашей лежит во второй коробке Пж помогите

Answer 1

Пусть : Х - третья коробка. 
Тогда  : вторая коробка 2 Х , а первая 0.5 Х.
Составим уравнение : 
Х + 2Х +0.5Х=63
3.5Х=63
Х=63/3.5
Х=18 )

Answer 2

Calculating the Number of Pencils in the Second Box

To calculate the number of pencils in the second box, we can use the information provided about the relative quantities of pencils in each box.

Let's denote: - The number of pencils in the first box as x - The number of pencils in the third box as y

Given: - The total number of pencils in all three boxes is 63: x + y + 2y + 0.5y = 63

Solving for y: - x + 3.5y = 63 - 3.5y = 63 - x - y = (63 - x) / 3.5

Now, we know that the number of pencils in the second box is twice the number of pencils in the third box: - 2y

Let's calculate the number of pencils in the second box using the formula we derived for y.

The number of pencils in the second box is 2 * ((63 - x) / 3.5).

Let's calculate the value.
