Question

ПОМОГИТЕ ПОЖАЛУЙСТА РЕШИТЬ!!! Реферат по физике Миша набирал на компьютере 3 дня. В первый день он набрал в 1,25 раза меньше листов, чем во второй, а в третий день- на 40% больше, чем во второй. Сколько всего листов содержал реферат, если в третий день Миша набрал на 6 листов больше, чем в первый?

Answer 1

Х - первый день
1,25х - второй день
1,25+1,4х - третий день
Запишем выражение:
1,25х+6=1,25*1,4х
1,25х+6=1,75х
1,75х - 1,25х = 6
0,5х = 6
х = 12 
...
12*1,25 = 15 
12*1,4 = 21  
12+15+21=48
Ответ:48 листов.

Problem Analysis

To solve this problem, we need to determine the total number of pages in the essay that Misha typed on his computer over three days. We are given the following information: - On the first day, Misha typed 1.25 times fewer pages than on the second day. - On the third day, Misha typed 40% more pages than on the second day. - On the third day, Misha typed 6 pages more than on the first day.

Let's break down the problem and solve it step by step.

Solution

Let's assume that the number of pages Misha typed on the second day is x.

On the first day, Misha typed 1.25 times fewer pages than on the second day, which means he typed x - 1.25x = 0.75x pages.

On the third day, Misha typed 40% more pages than on the second day, which means he typed x + 0.4x = 1.4x pages.

On the third day, Misha typed 6 pages more than on the first day, which means he typed 0.75x + 6 pages.

To find the total number of pages, we need to add up the number of pages typed on each day: Total pages = (pages on the first day) + (pages on the second day) + (pages on the third day)

Total pages = (0.75x) + x + (1.4x) = 3.15x

We also know that on the third day, Misha typed 6 pages more than on the first day: 0.75x + 6 = 1.4x

Solving this equation will give us the value of x, which we can then substitute into the equation for the total number of pages to find the answer.

Let's solve the equation:

0.75x + 6 = 1.4x

Subtracting 0.75x from both sides: 6 = 0.65x

Dividing both sides by 0.65: x = 9.23

Now we can substitute the value of x into the equation for the total number of pages: Total pages = 3.15x = 3.15 * 9.23 = 29.09

Therefore, the total number of pages in the essay is approximately 29.

Answer

The total number of pages in the essay that Misha typed on his computer over three days is approximately 29.
