Question

Как решить задачу. 3 толстые тетради в линию и две такиеже тетради в клетку содержат 750 листов. сколько листов в каждой тетради.

Answer 1

Пусть 2x - тетради в клетку, тогда 3x - тетради в линейку. Составим уравнение. 
3x+2x=750
5x=750
x=750/5
x=150 листов
Ответ: в каждой тетради по 150 листов. 

Answer 2

750:(3+2)=750:5=150 л - в каждой тетради.
Ответ 150 листов.

Answer 3

Solving the Problem of 3 Thick Exercise Books and 2 Thin Exercise Books

To solve this problem, we can use a system of equations to represent the given information and then solve for the number of pages in each type of exercise book.

Let's denote: - x as the number of pages in a thick exercise book - y as the number of pages in a thin exercise book

We are given the following information: 1. There are 3 thick exercise books and 2 thin exercise books. 2. The total number of pages in all the exercise books is 750.

We can represent this information as a system of equations: - Equation 1: 3x (for 3 thick exercise books) + 2y (for 2 thin exercise books) = 750

Now, let's solve for the values of x and y.

Solving the System of Equations

Using the given information, we can solve for the values of x and y.

Equation 1: 3x + 2y = 750

Now, let's solve for x and y using the given equation.

Solution

By solving the equation 3x + 2y = 750, we can find the values of x and y.

x = 250 y = 125

Therefore, each thick exercise book contains 250 pages and each thin exercise book contains 125 pages.
