Which master can give me the Luke version of junior high school math synchronous practice, the first

What is the first grade? And I can't take a screenshot.

I.1（1）800 （2）50 2.(1) 3 (2) 8:30-9:00 and 10:00-10:30

3.Slightly 4(1) 3 (2) 1 30 (3) (50 + 150 + 250) 3 = 150 (kmh).

4) 50-0 = 50 (km-h) 150-50 = 100 (km-h) 250-150 = 100 (km-h).

A: ...II. Omitted.

We've just done it too.

How to send that.

Do a 38-page 1:320 divided by 5|2=800 (Ben).

2:320 divided by 3|4 = 240 (Ben).

The first brigade of Changfeng Farm has 23 hectares of land, and plans to use 10 percent of the land to grow cotton, and the rest of the land to grow corn and soybeans. (1) How many hectares of corn are planted and the land that is impressed??? 2) If the land on which corn is grown is 60% of the land where corn is grown and soybeans combined, how many hectares of land is used to grow soybeans???

Child, think about it yourself, you really don't ask even questions.

You're already a college student, so how can you still let others give you advice and opinions? How much do others know about you? It's you who knows you best.

You should calm down and analyze your strengths, strengths, potentials, and even some characteristics that are different from others, etc., and choose the professional field that you are interested in in the future, and then choose which major to take. In this way, on the one hand, you are not confused in the preparation stage for the graduate school entrance examination, and you will not easily deny your choice; On the other hand, during graduate school, you will not be in the same situation as you are at this stage of study.

No matter how much detailed information is provided by others, it is not based on what they know about you, but on what they know. Again.

There are no questions, who will help you find a synchronous special training ......

The question stem is incomplete and lacks the question, so it cannot be answered normally.

The ultimate success.

It's up to you.

Don't pin your hopes on answers.

Good luck with your learning and progress.

Eq. (3-m) x (|m|-2) +7=2 is a unary equation then 3-m≠0,|m|-2=1

m≠3,|m|=3

m≠3,m=±3

So m=-3

I have to buy a copy by myself, and I can't find it online.

In fact, I can't give it to you, you can't learn math if it's so impetuous. If you want to answer the right answer, you have to wait for the teacher to explain, which is definitely much better than the right answer.

Students who have watched the TV series "Journey to the West" must like Sun Wukong's "Ruyi Golden Hoop Stick", which can be retracted at will, assuming that it is only 1cm at the shortest, 3cm after a change, 9cm after a second change, and 27cm after a third change....If you continue to change like this, you will not be able to use it until you have changed it a few times?

Go buy it!! That's a good idea!

You go to the bookstore and buy the answer for 10 yuan a copy.
