Question

В первый день Вася решил х примеров, во второй день в 2 раза больше, чем в первый , а в третий на 12 примеров меньше, чем во второй. Всего за три дня он решил 48 примеров. Сколько примеров Вася решил в третий день?

Answer 1

В первый 12, во второй 24, в третий 12 

Answer 2

Х+2х+(2х-12)=48
х+2х+2х-12=48
5х=60
х=60/5
х=12примеров -в 1 день
2*12-12=24-12=12-в третий

Answer 3

Problem Analysis

We are given information about the number of math problems Vasya solved on three consecutive days. On the first day, he solved x problems. On the second day, he solved twice as many problems as on the first day. On the third day, he solved 12 problems fewer than on the second day. We need to determine how many problems Vasya solved on the third day.

Solution

Let's break down the information given: - On the first day, Vasya solved x problems. - On the second day, he solved twice as many problems as on the first day, so he solved 2x problems. - On the third day, he solved 12 problems fewer than on the second day, so he solved 2x - 12 problems.

We are also given that Vasya solved a total of 48 problems over the three days.

To find the number of problems Vasya solved on the third day, we can set up the equation: x + 2x + (2x - 12) = 48

Simplifying the equation: 5x - 12 = 48 5x = 60 x = 12

Therefore, Vasya solved 12 problems on the third day.
