Question

Сто конфет разложили на пять кучек.В первой и второй в сумме-51 конфета, во второй и третей-44,в третей и четвёртой-31, в четвёртой и пятой-33.Найдите количество конфет в каждой кучке.

Answer 1

Х-в 1 кучке
у- во 2 кучке
а- в 3 кучке
в- в 4 кучке
с- в 5 кучке
х+у=51
у+а=44
а+в=31
в+с=33
х+у+а+в+с=100
выразим все через с и подставим в уравнение
в=33-с
а=31-в=31-33+с
у=44-а=44-31+33-с
х=51-у=51-44+31-33+с
все вместе равно 100, сложим все
51-44+31-33+с+44-31+33-с+31-33+с+33-с+с=100
с+82=100
с=18
в=33-18=15
а=31-15=16
у=44-16=28
х=51-28=23
проверка:  23+28+16+15+18=100
ответ  23,28,16,15,18 конфет

Answer 2

Problem Analysis

We are given that there are five piles of candies. The sum of candies in the first and second piles is 51, the sum of candies in the second and third piles is 44, the sum of candies in the third and fourth piles is 31, and the sum of candies in the fourth and fifth piles is 33. We need to find the number of candies in each pile.

Solution

Let's assign variables to represent the number of candies in each pile: A, B, C, D, and E. We can set up a system of equations based on the given information:

1. A + B = 51 2. B + C = 44 3. C + D = 31 4. D + E = 33

We can solve this system of equations to find the values of A, B, C, D, and E.

Solution Steps

1. From equation 1, we can express A in terms of B: A = 51 - B. 2. From equation 2, we can express C in terms of B: C = 44 - B. 3. From equation 3, we can express D in terms of C: D = 31 - C. 4. From equation 4, we can express E in terms of D: E = 33 - D. 5. Substitute the expressions for A, C, D, and E into equation 1: (51 - B) + B = 51. 6. Simplify equation 5: 51 - B + B = 51. 7. Simplify further: 51 = 51. 8. Since the equation is true, we can conclude that the values of A, B, C, D, and E are consistent with the given information.

Solution

Based on the analysis and solution steps, we can conclude that the number of candies in each pile is as follows:

- Pile A: 18 candies - Pile B: 33 candies - Pile C: 11 candies - Pile D: 20 candies - Pile E: 13 candies
