Answer 1

1) 150 - 50 = 100 стр  - во второй книге

2) 150+100= 200 стр  - в первой и второй книгах вместе

3) 200+70 = 270 стр - в третьей книге

1) 150 - 50 = 100 с - у другій книзі

2) 150+100= 200 стор - у першій та другій книгах разом

3) 200+70 = 270 стор - у третій книзі.

Answer 2

Calculation of the Number of Pages in the Third Book

To determine the number of pages in the third book, we need to consider the information provided about the first and second books.

Let's denote the number of pages in the first book as x.

According to the given information: - The second book has 50 pages less than the first book, so it has x - 50 pages. - The third book has 70 pages more than the first book and the second book combined. Therefore, the third book has (x + (x - 50)) + 70 pages.

To find the number of pages in the third book, we can simplify the equation:

x + (x - 50) + 70 = 3x - 50 + 70 = 3x + 20

Therefore, the number of pages in the third book is 3x + 20.

Now, we need to find the value of x to calculate the exact number of pages in the third book.

Unfortunately, the provided search results do not contain the specific information needed to determine the value of x or the number of pages in the third book. Therefore, we cannot provide an exact answer based on the available information.
