Answer 2

Problem Analysis

We are given the following information: - Vanya is 6 cm taller than Sasha. - Sasha is 7 cm taller than Andrey. - The sum of their heights is 452 cm.

We need to find the height of each boy.

Solution

Let's assume the height of Andrey is x cm.

According to the given information: - Sasha's height = Andrey's height + 7 cm - Vanya's height = Sasha's height + 6 cm

We can express their heights in terms of x: - Sasha's height = x + 7 cm - Vanya's height = (x + 7 cm) + 6 cm = x + 13 cm

The sum of their heights is 452 cm: x + (x + 7) + (x + 13) = 452

Simplifying the equation: 3x + 20 = 452 3x = 432 x = 144

Now we can find the height of each boy: - Andrey's height = x = 144 cm - Sasha's height = x + 7 = 144 + 7 = 151 cm - Vanya's height = x + 13 = 144 + 13 = 157 cm

Therefore, the height of each boy is: - Andrey: 144 cm - Sasha: 151 cm - Vanya: 157 cm

Answer

The height of each boy is as follows: - Andrey: 144 cm - Sasha: 151 cm - Vanya: 157 cm
