The questions of the junior high school mathematics test, the first junior high school mathematics t

Hello classmates. Now think about the saying of the ancients: If people have no foresight, they must have near-term worries.

Makes sense. But at present, it is only a period of time, and there are still many opportunities to work hard immediately, so don't be nervous and discouraged. But I would advise you to approach every exam with a sense of normalcy, just treat it as a practice and add up to any problems you find.

The night before the exam, don't stay up late and work overtime, so that you don't have a better and more energy to deal with the exam the next day. If you have time, review the textbook and your own notes, don't do the questions anymore, you may be happy to do it; But this can only be a kind of review for you; No, you will feel that you have not studied well before, give yourself a wrong judgment, and interfere with your emotions in answering questions the next day.

When answering the math test paper, you must answer the questions carefully and quickly, and carefully consider every sentence in the question. After answering, check again, and then change your thinking about the multiple-choice questions and change them into substitution methods to see if your conclusions are in line with the question; For example, when I took the college entrance examination, the last question, I felt very simple for the first time, I thought it was a bit impossible, I thought it was a little impossible, I thought it was a little impossible, and I thought about it carefully, and in the last fifteen minutes I found its test point, I answered it, and I got this precious fifteen points.

Tonight, let's quickly review the basics, classic question types, and the questions I did wrong before2 Get up tomorrow as usual, don't have to get up early, don't get up late, 3 Pay attention to the problems when doing the questions, if you have no clue to skip it, you just finish the simple ones first, and then you can't do them. The multiple-choice questions should also be finished. In fact, this is all well known, and there is no experience.

You can write down some unmemorized formulas in the book in advance, and if you find them, you can say that you came up with them during the exam.

Just rest well, and you can tell you're nervous by reading what you write.

No questions to do. For someone like you who is particularly concerned about exams, mental peace is the most important thing!!

When answering the paper, you should believe in your first impression, and secondly, don't have blank questions, and the teacher may give marks to any random writing, and one point is also a point!

Remember!!

1. Re-understand the ideas of the math problems that you have done wrong before; 2. Don't deliberately get up early 3. Do the questions carefully, strive for what you will do must be right, and you must not panic if you don't do it. In fact, sometimes math is also very inspirational, keep your thinking clear, and a problem that you would not otherwise do will still be thought of in the end. Pick the questions you know how to do first, and quickly develop self-confidence first, self-confidence comes, and inspiration follows.

Don't study too late at night, go to bed early, and read the key points when you read!

Just wake up in the morning, don't be nervous!

Do what you will do first, do the difficult questions later, don't stick to a question.

You can go for a walk at night, go to the playground to run a few laps is nothing, so you can sleep well, get up in the morning as usual, don't arrange anything, don't be impetuous, some difficult to calculate put down first, time to arrange, I hope you can do well.

Get a good rest and get some sleep. Don't be nervous and don't be sloppy when doing the questions. The easy ones and then the hard ones can increase your confidence. Don't take it to heart, just keep a normal heart.

You should do what you should do at night tonight, just be normal, excessive review even if the test is over-level performance can not really reflect your learning situation, the exam is a test of your usual learning, good grades are not the most important.

1.In the evening, you can read the basic formulas and simple questions.

2.Normal onwards.

3.Carefulness is the most important thing, and it is good not to have mistakes caused by carelessness.

Go to bed early today, and don't ask questions you don't understand when you enter the exam room, and don't think about any questions that require you to think about. This is the only thing to believe in is your self-confidence.

Solution: There are x male employees and y female employees.

According to the total score, the square silver is equal to Ctrip.

80x+x=7y/10

x and y are both integer volts and 80 (x+y) 90x=35 and y=50

A: There are 35 male employees and 50 female employees.

Hope it helps you and branches! Hope!

Let ec=x

Right angle triangle ECB medium angle EBC = 30 degrees.

bc=x√3

Right angle triangle d cb middle angle dbc = 60 degrees.

dc =tan60 *bc=3x

Tower height dc-ec =2x

Right angle triangle da c middle angle dac = 45 degrees.

dc=ac3x=ab+bc=

Requested. The tower height is 2x=

Original = (y+2) + root number = 0

Because both are greater than or equal to 0.

So y+2=0

x+y-1=0

The solution yields x=3 y=-2

So xy=-6

It's not hard to ......

y +4y+4=(y+2) 0, root number (x+y-1) 0 to be 0, can only be 0

y=-2,x=3

xy=-6

In this case, pm+pn=mn' is a line segment, and when p takes another point p' on the y-axis, p'm+p'n

p'm+p'n'>mn', when p is on mn', pm+pn=mn' is the smallest.

Equivalent to the milk station problem of the first day of junior high school, the shortest distance is plotted, and the two points of the symmetry point coordinates (-3, 2) (1, -1) of the y-axis are determined to find the analytical formula, and the intersection point is on the y-axis, then the abscissa is 0
