Question

Пожалуйста помогите мне! Три кубика и раковина весят столько же,сколько 12 шариков, а одна раковина-столько же,сколько 1 кубик и 4 шарика. Сколько шариков уравновесят раковину????

Answer 1

3к +р = 12ш 
1р = 1к +4ш 
 Из первого находим  
1р = 12ш -3к,
А из втрого  
1к = 1р - 4ш,
подставляем  1р = 12ш - 3 (1р -4ш) = 12ш -3р +12 ш 
4р = 24 ш 
1р = 6ш 

Answer 2

Problem Analysis

To solve this problem, we need to determine the number of balls that will balance the weight of the sink. We are given the following information: - The weight of three cubes and the sink is equal to the weight of 12 balls. - The weight of the sink is equal to the weight of one cube and four balls.

Let's assign variables to the unknown quantities: - Let's denote the weight of one cube as C. - Let's denote the weight of one ball as B. - Let's denote the weight of the sink as S.

Based on the given information, we can write the following equations: 1. 3C + S = 12B (Equation 1) 2. S = C + 4B (Equation 2)

We need to solve
