Question

Три неразлучных друга - Винни-Пух ,Кролик и Пятачок -решили узнать свой вес.Но шкала весов до 20 кг была повреждена, и показания по ней прочитать не представлялось возможным .Поэтому Винни Пух взвесился сначала с Кроликом: получилось 22,4 кг;затем с Пятачком ,получилось 23,5 кг; а затем они взвесились все вместе и получили 26,7 кг.Какова масса каждого из них в отдельности?СРОЧНО

Answer 1

26.7-22.4=4.3 весит пяточок

23.5-4.3=19.2 весит винни

Problem Analysis

Three friends - Winnie the Pooh, Rabbit, and Piglet - want to determine their individual weights. However, the weight scale they have can only measure up to 20 kg, and it is damaged, making it impossible to read the measurements directly. They decide to weigh themselves in pairs and then all together to find out their individual weights.

Solution

Let's assume the weights of Winnie the Pooh, Rabbit, and Piglet are represented by the variables W, R, and P, respectively.

1. Winnie the Pooh weighs himself with Rabbit and the total weight is 22.4 kg. - W + R = 22.4 kg 2. Winnie the Pooh weighs himself with Piglet and the total weight is 23.5 kg. - W + P = 23.5 kg 3. All three friends weigh themselves together and the total weight is 26.7 kg. - W + R + P = 26.7 kg To find the individual weights of Winnie the Pooh, Rabbit, and Piglet, we can solve these three equations simultaneously.

Solving the Equations

We can use substitution or elimination to solve the equations. Let's use the substitution method.

From equation 1, we can express R in terms of W: R = 22.4 - W

Substituting this value of R into equation 3, we get: W + (22.4 - W) + P = 26.7 22.4 + P = 26.7 P = 26.7 - 22.4 P = 4.3 kg

Substituting the value of P into equation 2, we get: W + 4.3 = 23.5 W = 23.5 - 4.3 W = 19.2 kg

Now we can substitute the values of W and P into equation 1 to find R: 19.2 + R = 22.4 R = 22.4 - 19.2 R = 3.2 kg

Answer

Based on the given information, the individual weights of Winnie the Pooh, Rabbit, and Piglet are as follows: - Winnie the Pooh: 19.2 kg - Rabbit: 3.2 kg - Piglet: 4.3 kg
