I m about to be in the eighth grade, ask for guidance! 8th grade math, urgent !!

Tutoring is not necessary, because according to what you said, your brother's foundation is too poor, and now there are very few good-natured teachers, it is better for you to teach him personally, before teaching, I hope you can calm your mood first, to accept the fact that your brother's foundation is not good, anger can not solve the problem, with a peaceful and encouraging tone, slowly teach him, if you have no confidence in him, there is no one to help him.

English phonetic transcription will not, and it does not have much impact, you can learn a little Chinese pinyin every day, and then learn phonetic transcription, in fact, English pronunciation phonetic transcription is just an auxiliary thing, the task is very arduous, then grasp little by little, start from the basics.

What you need may not be guidance, but support, because the knowledge of primary and junior high school is not very difficult, and you can tutor him.

It's easier said than done, but I'm sure you can do it, as the saying goes.

When you truly desire something, the whole universe will unite to help you.

Buy him a book of pure arithmetic problems, from simple to complex.

English phonetic transcription is good on the Internet, and there must be the kind of pronunciation + words, and teach him one by one. Or find him a phonetic alphabet teacher.

Chinese pinyin should be made up after the phonetic transcription is fully learned, which is also more important.

Learn to be patient first, your brother can't you ask a teacher to teach him, you have to show him that learning is a pleasure. You have to give him confidence and encouragement. At the same time, you have to be patient to understand him, why he can't learn well, and come up with a way to make your brother accept it.

It's still okay to find a tutor.,Actually, according to what you say, I think he's still good.,It's all in the eighth grade.,Even 3+1 has a problem.,So what else to learn.。

You can only start from the basics of elementary school.

You can ask some tutors, preferably some students, so that it is easier to get along at this age, and you should dictate more in English.

3 4 5 is a right-angled three-late spring horn.

3*4=5*x

The hypotenuse on the high yard and the resistance x is 12 5

So for Shedhor 3:4:12 5

Set the height of the flagpole to x

According to the Pythagorean theorem.

Root number x +8 = root number (x + 2).

Both sides are squared ......

x=15

The addition of 2 to 6 is equal to 8 so the height is 6

15m, let the height ab be h, then ac is h+2, and because bc=8, there is an equation: h square + 8 square = (h + 2) square, solve the equation to get h = 15 meters.

It's easy, here's the thing:

1. Solve the inequality to get x 3 2, then the negative integer is 1;

(8 6) = that he needs to walk at least every hour;

3. Solve the inequality x-1 a to get x 1 a, so that the inequality has four non-negative integers to solve, 1 a=3, a=2;

4. The solution set of inequality x <1 is 1 x 1.

5、(1)x-1/3-2x+5/4>-2

Solution: Remove the denominator to get: 4(x-1)-3(2x+5)-24 without parentheses: 4x-4-6x-15 -24

Move the items and merge the same kind of items to get: -2x -5

The coefficient is reduced to 1 to obtain: x 5 2

2)2x-1/3-5x+1/2≤1

Solution: Remove the denominator to get 2(x-1)-3(5x+1) 6 to get the parentheses: 2x-2-15x-3 6

Move or merge items of the same kind to obtain: -13x 11

The coefficient is reduced to 1 to obtain: x -11 13

6. Why is there no equal sign for the system of equations in the question?

7. Solve equation 3 (x-2a) + 2 = x-a+1 to obtain x=(5a-1) 2 substituting the inequality x-5 2 4a to obtain: (5a-1) 2-5 2 4a to obtain a -2

Now that computers are developed, children are studying hard, and their homework is posted online for others to do.

As for winning the championship, it's a reward for my years of hard work, so I'm very happy.

First of all, you have to show respect for your opponent, and then you have to express your joy after winning the championship. 6 Example: Happiness is a word of encouragement from the teacher Happiness is a warm reassurance from the mother (note that the sentence pattern should be the same.)

7 The first time "my eyes were moist" was because "I" was moved by the style of osmanthus; The second time, "many of us' eyes were moistened," was because "we" were moved by the old man's spirit of doing good in silence. 8 Prepare the way for the following writers. 9 With the title of "Dark Fragrance", the semantic pun is intriguing, which not only praises the unassuming quality of the dark fragrance of osmanthus, but also praises those ordinary people who are silently dedicated like osmanthus, highlighting the center of the article.

14 Because the situation was constantly changing, and he did not know how to apply his knowledge flexibly to the specific situation, he would only stick to the books, so he failed. 15. We should know how to be new.

Connecting a8 and a6, the sum of the internal angles of the heptagon is 900° from the sum of the internal angles of the polygon (n-2)*180

a1a8a6= a8a6a5=(900°-5*135°) 2=in a8a6a7.

a8a7a6=135°

Angle A7 = 360°-135° = 225°

Solution: Connect the two points of a3a7, then in the two pentagons, the sum of the internal angles of the left pentagon is: a1 + a2 + a31 + a71 + a8 (decompose the angles a3 and a7 into two angles) = (5-2) * 180°......

In the same way, the inner sum of the right pentagon is: a32+ a4+ a5+ a6+ a72=(5-2)*180°......

, a1 + a2 + a3 + a4 + a5 + a6 + a8 + a7 = 1080°

That is, 135°*5+90°*2+ a7=1080°, a7=225°

c=2

c=2+(p-1)* p> Qing calendar 1

So c=p 2+

So y=-2x+20

0y<2x is 2x<20=2x+y<4x50 y>0, so 0s=4y=12 y=3 x=7 p(7,3)4Obviously, it is more cost-effective to ship from B to C, and D is more cost-effective than A.

B is shipped to C240 tons, D 60 tons, A all 200 tons are shipped to D, and it costs a total of 240 * 15 + 60 * 24 + 200 * 25 = 10040 yuan.

Solution: Extinction x + 1 Posture cavity x = 17 x +2 + (1 x) = 17

x²+1/x²=15

x²+1/x²)=√15

Square both sides of the original equation Qi Lu ridge at the same time.

x 2+2+(1 muffled x) 2=17

x^2+1/x^2=15

The answer is root number 15

is the root number hypertonic 3 times the root number 5
