Question

Ученик получил в школьной библиотеке книгу в которой 265 страниц и прочитал её за шесть дней.В первые пять дней он прочитывал одинаковое количество страниц,а в последний-на 5 страниц меньше,чем в пятый день.Сколько страниц ученик прочитал за первые два дня? Мне срочно помогите пожалуйста!!!!​

Answer 1

Ответ:

Пошаговое объяснение:

5x + x - 5 = 265

6x - 5 = 265

6x = 265+5

6x = 270

x = 270:6

x = 45 страниц прочитывал в первые 5дней

45*2 = 90 страниц ученик прочитал за первые два дня

Answer 2

Problem Analysis

The student read a book with 265 pages in six days. During the first five days, the student read the same number of pages each day, and on the last day, the student read 5 pages less than on the fifth day. We need to determine how many pages the student read during the first two days.

Solution

Let's assume that the number of pages the student read each day for the first five days is x. On the sixth day, the student read 5 pages less than on the fifth day, so the number of pages read on the sixth day is x - 5.

To find the total number of pages read in six days, we can sum up the number of pages read each day:

x + x + x + x + x + (x - 5) = 265

Simplifying the equation:

6x - 5 = 265

Now, we can solve for x:

6x = 270

x = 45

Therefore, the student read 45 pages each day for the first five days.

To find the number of pages read during the first two days, we add the number of pages read on the first day and the number of pages read on the second day:

45 + 45 = 90

So, the student read 90 pages during the first two days.

Answer

The student read 90 pages during the first two days.
