Question

Составь два уровнения одно с неизвестным делителем а другое с неизвестным множителем с которым можно будет решить следущую задачу. Для школьной библиотеки купили 45 книг заплатив 2250руб. Какова цена одной книги

Answer 1

45×x=2250
x=2250:45
x=50;значит цена книги 50 рублей
2250:x=45
x=2250:45
x=50

Answer 2

2250:45=50 
Ответ 50 рублей цена одной книги

Answer 3

Formulating Equations with Unknown Divisor and Multiplier

To solve the given problem, we can formulate two equations: one with an unknown divisor and the other with an unknown multiplier.

Let's denote the unknown divisor as x and the unknown multiplier as y.

We know that the total cost of 45 books is 2250 rubles. Therefore, the equation with the unknown divisor can be represented as: 45x = 2250

Similarly, the equation with the unknown multiplier can be represented as: y * 45 = 2250

Solving the Equations

Now, let's solve these equations to find the values of x and y.

For the equation 45x = 2250: x = 2250 / 45 x = 50

For the equation y * 45 = 2250: y = 2250 / 45 y = 50

Conclusion

The price of one book is 50 rubles. This is the solution to the given problem, and it can be verified by substituting the value of x or y back into the original equation.
