Who s going to help me out? To the process.

You don't have any questions, what are the answers? Are the reward points an exhibit?

Pony 2... What a novel creature is that...

3 unknowns, 2 relations, and the answers are not fixed.

You can first solve the title:

100 horses, 100 tiles, 3 large camels, and two ponies carrying one. Q: How many big horses and ponies are there? Then replace the big horse and the pony with the second horse.

Count below the number of 100 horses and ponies carrying a total of 100 tiles, horses and ponies.

100*3-100) (Assuming that all are Malaysian's solutions.......)80 ponies and 20 horses were to carry a total of 100 tiles.

The number of pack tiles.

Malaysia: Two Horses: Ponies = 3:2:

First, if we replace the quantitative relationship between an equal number of ponies and horses with two horses, 3-2) :(3 ......It's hard to understand, think about ......

Yes, the number of tiles for 5 horses is the same as for 3 horses and 2 ponies.

Then replace 3 large horses and 2 small horses with 5 second horses with an equal relationship.

Get a series of data, 20 0 80

Hopefully, for the sake of such a hard work!

Solution: Set up big horses, medium horses, and small horses each have A, B, and C horses.

a+b+c=100 ①

3a+2b+c/2=100 ②

2 gets 6a+4b+c=200

Get 5a+3b=100

a=20-3b/5≥0

b≤30b
a
c

Thus, there are 7 groups in total.

Malaysia has , 11, 8, 5, 2

There are middle horses and small ponies have

If you want to have them, then you have to remove this group

If you don't have a master, help you solve it, and if you want the process, you can ask your teacher and let him not help you.

This question can be used.

Analytically proves the inequality.

Here's how to solve it!

Got it.

Open the root number, 2 opened the root number, and then multiply by 3, the result is, plus 4 is, this is calculated according to 3 times the root number 2, because it looks like what you write is not like opening 3 power.

；Subtract the two to see if the result is greater than 0.

The dumber way is to honestly calculate the derivative step by step and bring in x=0

Associative Law Add 2 and 3/7 and 2 and 4/7 to get 5, and then.

The one on the right adds 5/12 and 7/12 to 1, and then 2/9 gives 1 and 2/9

Question 4:

Analysis: Laughing Uncle Zhang.

I am 7 years old and 33 years old.

After x years 7+x 33+x

The key to solving equations is to find equiquantity relations; Uncle Zhang is 3 times older than Xiaoxiao after X years, according to this equation of the equivalence off series:

3(7+x )=33+x

Therefore, this question is selected: b

Question 5: Bring x=3 into the given option, choose a. Mathematics is generally a multiple-choice question, and you don't need to count it down after confirming that it is A.
