A mathematical problem requires detailed explanation It is known that class A has six more people than class B, and class B has three more people than class C. now, group A of class a goes to class B, group A of class B goes to class C, and group 1 of class C goes to class A. in this way, the number of people in the three classes is equal. It is known that class C goes to class A with four people. How many people are there in class A and group 1 of class B? Don't set X to ask for detailed explanation every step
6 + 3 = 9 (more a than C)
9 + 3 = 12 (the total number of a and B is more than C)
12 / 3 = 4 (C needs to increase)
4 + 4 = 8 (number of group B)
9 + 4-4 = 9 (group number of class a)
There are 28 walnuts in group A, 30 walnuts in group B and 31 walnuts in group C. The total number of walnuts in the three groups is 365. How many students are there in the three groups?
There are a group of students a, B group of students, C group of students; 28 (a + B + C) < 28a + 30b + 30b + 31C = 365 a + 30b + 31C = 365, get a + B + C < 36528 < 13.04 < 13.04 < 13.528 < 13.04 < 13.04 < 13.04 < 13.04 < 13.04 < 13.04 < 13.04, then 28a + 30b + 30b + 31C = 28 (a + 30A + 30A + 30b + 30b + 30A + 30b + 30b + 31a + 30b + 31a + 30b + 30b + 30b + 31C = 2828a + 30A + 30A + 30A it is shown that the formula is: a = 28 (a + B + C) + 2B + 3C = 28 × 13 + 2B + 3C = 365, that is, 2b + 3C = 1 There is no solution to the equation. A: there are 12 students in the three groups
A shopping mall held a shopping lucky draw to attract customers. There are three kinds of prizes: 1000 yuan for the first prize, 250 yuan for the second prize and 50 yuan for the third prize. A total of 100 people won the lottery, with a total amount of 9500 yuan. How many of them won the second prize?
According to the Title Meaning: x + y + Z = 1001000x + 250Y + 50z = 9500, eliminate Z, 9.5x + 2Y = 45, this equation is indefinite, according to the title meaning x, y, Z are natural numbers, try to give the value of X, only when x = 2, y = 13, in line with the title meaning
In the duality of labor in the production of goods, concrete labor forms () of goods, abstract labor forms () of goods
In the duality of labor in the production of goods, concrete labor forms the (use value) of goods, and abstract labor forms the (value) of goods
Why does abstract labor reflect the economic relationship between commodity producers?
Abstract labor is a kind of non concrete human labor, which creates the value of goods. The exchange of labor products between commodity producers is not only the comparison of product quantity, but also the comparison of labor quantity. Therefore, in the long process of exchange, different forms of concrete labor gradually return to the same
Commodity value is the general human labor that a condenses in commodities, B reflects the production relationship between commodity producers, C is the basis of D exchange value formed by abstract labor

4. The difference between concrete labor and abstract labor is () A. concrete labor is the concrete form of labor, and abstract labor is general human labor B. concrete labor is physical labor, and abstract labor is mental labor C. concrete labor reflects the relationship between human and nature, and abstract labor reflects social relationship D. concrete labor is the natural attribute of labor, and abstract labor is the social attribute of labor

If a commodity producer's individual labor time for producing a commodity is equal to the social necessary labor time, then in commodity exchange:
A is bound to lose money; B is bound to make money; C is not going to lose money; D is likely to make money or lose money
D! Social necessary labor time is only the reference system of price! Price is affected by many factors
What is concrete labor and what is abstract labor?
Don't copy, don't use the words in the book!
If I can read books, I won't ask questions here
Give more practical examples
