Answer 3

Problem Analysis

To solve this problem, we need to determine the height difference between Sasha and Andrei. We are given the following information: - Tolya is 5 cm taller than Andrei. - Petya is the same height as Tolya but 3 cm shorter than Sasha.

Let's represent the heights of Andrei, Tolya, Petya, and Sasha as A, T, P, and S, respectively.

Solution

1. We know that Tolya is 5 cm taller than Andrei, so we can write the equation: T = A + 5. 2. We also know that Petya is the same height as Tolya but 3 cm shorter than Sasha, so we can write the equation: P = T = S - 3.

To find the height difference between Sasha and Andrei, we need to subtract Andrei's height from Sasha's height: S - A.

Let's substitute the values from the equations above to find the height difference.

Substituting T = A + 5 into the equation P = T = S - 3, we get: A + 5 = S - 3.

Simplifying the equation, we have: S = A + 8.

Now we can substitute this value of S into the height difference equation: S - A = (A + 8) - A = 8.

Therefore, Sasha is 8 cm taller than Andrei.
