What are the mottos for classrooms, stairs, and restaurants? and give reasons. Hurry, hurry, hurry

Teachers – study well.

Restaurant - people are iron, rice is steel, and if you don't eat a meal, you will be hungry. Rice is based on food.

The purpose of the student is to be inquisitive.

We have winter vacation homework in our books.

18. The scale is large, the equipment is advanced, and the books are not borrowed.

19. The practice and benefits of the books of the National Library of France "are not loaned, but only for reference". The use of "first", "second" and "second" makes the article structured rigorously and hierarchically; From primary to secondary, it reflects the logical order.

20. Make comparisons, list numbers, and divide categories The National Library of France has many seats and good conditions.

Paragraphs 21, B22, and 7 describe the computer network installed by the library and its function, while paragraph 8 describes the fact that further entry of the bibliography into the network and its significance is being considered.

23. Use your imagination and creativity to design an internal facility by yourself.

This question is easy to illustrate with a picture, depending on your understanding, let me say something. Both sides of the boat are subjected to the pressure of the water and are equal in size and in opposite directions. Adjust the direction of the sail to between due northeast and east, then the wind force on the sail can be decomposed into a force perpendicular to the sail, a force parallel to the sail, the parallel force is useless, the perpendicular force direction is between the northwest direction and the north, and the combined force of this force and the force of the water on the left side of the ship can be towards the northeast.

Got it? It should be understandable to draw a picture.

Set up a military baix family, then there are 2x bags of brown sugar du, and zhi5x+10 bags of white sugar. Cube dao according to the title

Range: 5x+10=2x*3

The solution is x=10

2x=205x+10=60

A: 20 bags of red sugar and 60 bags of white sugar.

If the number of brown sugar bags is x, then the number of white sugar bags is 3x

x/2=3(x-10)/5

The solution is x=60

So the number of brown sugar bags is 60 bags, and the number of white sugar bags is 3 * 60 = 180 bags Answer: ......

20 bags of brown sugar and 60 bags of white sugar.

Set red x bags and white sugar on 3x

x 2=(3x-10) 5 is fine.

I'm doing the same question with the answer.

Let life be more grinding, mainly in the hope that we can experience more hardships in life. Mencius said: Born in sorrow, die in peace.

Most of the people who can go through hardships can achieve extraordinary careers. It is hoped that those who have aspirations can learn successful lessons from the tribulations and achieve the glory of their lives and careers.

This type of question is subjective and needs to be combined with the text.

It is to let life test yourself more, and only after experiencing wind and rain can you see the rainbow.

1. (502+242) 16=seconds).

1245 = 2565 (yuan) (This is the money that each student in this class needs for a year and a half.) ）

yuan) (each person needs 45 yuan for a year and a half).

2565 45 = 57 (person).

(242+502)/16

Half-year 15 full year 30

Set up x people for half a year and y people for the whole year.

15x+30y=1320

15y+30x=1245

Solve the system of equations to obtain: x+y=?

One (242 + 502) 16=

26 people for half a year. 31 people per year.

1. (502+242) 16=seconds).

1245 = 2565 (yuan).

Yuan) 2565 45 = 57 (person).

Please smile.

1,,,502+242)/16=

Then it's time to solve the equations.
