Answer 1

Груши= Х
Апельсины= 2Х
Яблоки= (2Х+3)
Всего фруктов= 8 кг
Яблок=? Кг

Х+2Х+(2Х+3)=8
5Х+3=8
5Х=8-3
5Х=5
Х=1 кг груш
2Х=1•2=2 кг апельсинов
2Х+3=2•1+3=5кг яблок

Проверка
Х+2Х+(2Х+3)=8
1+2•1+(2•1+3)=8
1+2+5=8
8=8
Ответ: мама купила 5 кг яблок

Problem Analysis

To solve this problem, we need to find the number of apples that the mother bought. We are given the following information: - The mother bought apples, pears, and oranges. - The mother bought twice as many pears as oranges. - The mother bought 3 kilograms more apples than oranges. - The total weight of the fruits bought by the mother is 8 kilograms.

Let's assume that the number of oranges bought by the mother is x. We can then express the number of pears bought as 2x (twice the number of oranges) and the number of apples bought as x + 3 (3 kilograms more than the number of oranges).

Solution

To find the number of apples bought by the mother, we can set up the following equation based on the given information:

x + 2x + (x + 3) = 8

Simplifying the equation:

4x + 3 = 8

Subtracting 3 from both sides:

4x = 5

Dividing both sides by 4:

x = 5/4

Since we cannot have a fraction of a fruit, we need to round the value of x to the nearest whole number. In this case, x is approximately 1.25, so we round it to 1.

Therefore, the mother bought 1 orange.

To find the number of apples, we substitute the value of x into the equation:

x + 3 = 1 + 3 = 4

Therefore, the mother bought 4 apples.

Answer

The mother bought 4 apples.
