Answer 1

Не уверенна в правильности,но я поняла эту задачу так. 
женских - любое число. Я взяла число 4
мужских  (3*4)
Всего тоже любое число. Я взяла число 20
детских-  х
Составляем уравнение:
4+3*4+х= 20
4+12+х=20
16+х=20
х=20-16
х=4
Ответ : 4 велосипеда детских
Если я неправильно поняла,то объясни. И ,думаю,я помогу тебе)

Answer 2

Problem Analysis

To solve this problem, we need to determine the number of children's bicycles in stock. We are given that there are a total of ? bicycles in stock, with the following information: - The number of women's bicycles is ?. - The number of men's bicycles is three times the number of women's bicycles. - The remaining bicycles are children's bicycles.

Solution

Let's assign variables to the unknown quantities: - Let W represent the number of women's bicycles. - Let M represent the number of men's bicycles. - Let C represent the number of children's bicycles.

From the given information, we can deduce the following relationships: - The number of men's bicycles is three times the number of women's bicycles: M = 3W. - The total number of bicycles is the sum of the women's, men's, and children's bicycles: ? = W + M + C.

To find the number of children's bicycles, we need to express C in terms of W: - Substituting M = 3W into the equation ? = W + M + C, we get ? = W + 3W + C. - Simplifying, we have ? = 4W + C. - Rearranging the equation, we find C = ? - 4W.

Now we have an expression for the number of children's bicycles in terms of the number of women's bicycles and the total number of bicycles.

Answer

To find the number of children's bicycles, we need to know the total number of bicycles in stock (?) and the number of women's bicycles (W). The number of children's bicycles can be calculated using the equation C = ? - 4W.

Please provide the values for ? and W, and I will calculate the number of children's bicycles for you.
