Question

На столе лежат яблоки и груши. Если добавить 34 яблока, то их станет вдвое больше, чем груш. Сколько груш надо убрать, чтобы их стало в вдвое меньше, чем яблок? ​

Answer 1

Логично, что если в задаче сказано, что если добавить 34 яблока, то их будет в 2 раза больше чем груш, значит что яблок было 34. А Груш было в 2 раза меньше. Поэтому 34:2 будет

Пошаговое объяснение:

34 х 2 будет 68 (если их в 2 раза больше)

68:2 будет 34 (груш) и (яблок) (было)

34:2 = 17

Я знаю что ответ 17, просто я не знаю как это точно записать

Answer 2

Problem Analysis

We are given that there are apples and pears on a table. If we add 34 apples, the number of apples will be twice the number of pears. We need to determine how many pears we need to remove in order for the number of pears to be half the number of apples.

Solution

Let's assume the initial number of apples is A and the initial number of pears is P. According to the problem statement, if we add 34 apples, the number of apples becomes A + 34, and this is twice the number of pears, so we have the equation:

A + 34 = 2P We need to find the number of pears we need to remove in order for the number of pears to be half the number of apples. Let's assume the number of pears we need to remove is x. After removing x pears, the number of pears becomes P - x, and this should be half the number of apples, so we have the equation:

(A + 34) = 2(P - x) Now we can solve this equation to find the value of x.

Solving the Equation

Let's substitute the value of A + 34 from equation into the second equation:

A + 34 = 2(P - x)

Expanding the equation:

A + 34 = 2P - 2x

Rearranging the equation:

2x = 2P - A - 34

Simplifying the equation:

x = (2P - A - 34) / 2

Now we can substitute the value of A from equation into the equation for x:

x = (2P - (A + 34)) / 2

Simplifying further:

x = (2P - A - 34) / 2

Now we can substitute the value of A + 34 from equation into the equation for x:

x = (2P - (2P)) / 2

Simplifying further:

x = -34 / 2

x = -17

Since we cannot have a negative number of pears, it is not possible to remove a negative number of pears. Therefore, there is no solution to this problem.

Conclusion

In order for the number of pears to be half the number of apples, it is not possible to remove a negative number of pears. Therefore, there is no solution to this problem.
