Answer 1

Р- х см, К-(х+5)см,С-(х+8)см. В сумме 385см. Получим уравнение х+х+5+х+8=385. 3х=372. х=124. значит рост С будет 124+8=132 см

Answer 2

Возраст Рамиза х см, Каяна 5+х, Сардара х+8.
х+х+5+х+8=385
3х=385-13
х=124
124+8=132(см)

Answer 3

Problem Analysis

We are given the heights of three boys: Kyanan, Ramiz, and Sardar. Kyanan is 5 cm taller than Ramiz, and Sardar is 3 cm taller than Kyanan. The sum of their heights is 385 cm. We need to find the height of Sardar.

Solution

Let's assign variables to represent the heights of the three boys: - Let R represent the height of Ramiz. - Since Kyanan is 5 cm taller than Ramiz, Kyanan's height can be represented as R + 5. - Since Sardar is 3 cm taller than Kyanan, Sardar's height can be represented as (R + 5) + 3, which simplifies to R + 8.

According to the problem, the sum of their heights is 385 cm. We can write this as an equation: R + (R + 5) + (R + 8) = 385

Now, let's solve this equation to find the height of Sardar.

Solving the Equation

R + (R + 5) + (R + 8) = 385 3R + 13 = 385 3R = 385 - 13 3R = 372 R = 372 / 3 R = 124

Therefore, the height of Ramiz (R) is 124 cm.

To find the height of Sardar, we can substitute the value of R into the equation: Sardar's height = R + 8 = 124 + 8 = 132 cm.

Answer

The height of Sardar is 132 cm.
