Question

Дима съел треть конфет, которые были в коробке, и ещё четыре конфеты. После этого в коробке осталось 12 конфет. Сколько конфет было в коробке сначала? РЕШИТЬ УРАВНЕНИЕМ!!!!

Answer 1

Ответ: 24 конфеты

Пошаговое объяснение:

x - все конфеты

$(x-\frac{x}{3}) -4 = 12$

$x-\frac{x}{3} = 16\\ 3x-x = 48\\2x=48\\x=24$

Answer 2

Ответ:

Пошаговое объяснение:

Все конфеты = х штук

Съел = 1/3х + 4 штук

Осталось = 12 штук

х - (1/3х + 4) = 12

х - 1/3х - 4 = 12

х - 1/3х = 12 + 4

3/3х - 1/3х = 16

2/3х = 16

х = 16 : 2/3

х = 16 * 3/2

х = 48/2

х = 24

Было всего = (х) = 24 штуки

Съел = (1/3х + 4) = 1/3 * 24 + 4 = 24/3 + 4 = 8 + 4 = 12 штук

Осталось = 12 штук

24 - 12 = 12

Answer 3

Problem Analysis

To solve this problem, we need to determine the initial number of candies in the box. We know that Dima ate one-third of the candies and then ate four more, leaving 12 candies in the box. We can solve this problem by setting up an equation.

Let's assume the initial number of candies in the box is represented by the variable x.

Equation Setup

According to the given information: - Dima ate one-third of the candies, which is (1/3)x. - Dima also ate four more candies, which is 4. - After Dima ate the candies, there were 12 candies left in the box.

We can set up the equation as follows: (1/3)x + 4 = 12

Solving the Equation

To solve the equation, we can isolate the variable x.

Subtracting 4 from both sides of the equation: (1/3)x = 12 - 4

Simplifying the right side of the equation: (1/3)x = 8

To isolate x, we can multiply both sides of the equation by 3: 3 * (1/3)x = 3 * 8

Simplifying the left side of the equation: x = 24

Answer

The initial number of candies in the box was 24.
