！！！Don t mix it up!! Where does the pocket money of elementary school students go?

Just look at the TV...

I'm an elementary school student and I've been saving money.

Can you quietly ask if it is a ** elementary school student?

Do you want to do a field survey?

How many samples do you need? What function curve is used for statistics?

Forex trading is the exchange of one country's currency with another's currency.

The foreign exchange market refers to the market for the trading of foreign currencies and bills denominated in foreign currencies.

Because (1+x) (9-x)=2 3

So 1+x=2(9-x) 3

So 3(1+x) = 2(9-x).

So 3+3x=18-2x

So 5x=15

So x=5

Let the natural number be x, according to the meaning of the title:

1+x)/(9-x)=2/3

Solution: x=3

1. Throw it on the ground, step on it a few times, tear it in half, draw a horse, and turn it into ashes.

2. Treat it with a positive attitude and give it some hope and strength.

3. Use the fate of pieces of paper as a metaphor for the fate of people. Teachers use this example to encourage students not to give up and to deal with setbacks with a positive attitude.

And this question is to make me look at things in two ways: it's paper, and just because it's on the ground doesn't mean it can't be used.

Two: it is trampled around in the place, and it does not carry a watch, it cannot write or draw on it, and third: it tells us that gold always shines.

1. Abandoned, belittled, found to be valued.

2. The principle of waste utilization.

3. Life is like this, it may be forgotten by the society, but remember that you are gold, and there will always be a shining side of gold, so you have to find that your point continues to extend, and it has become your own bright spot.

I was born with a mindset that would be useful.

Think about things from a positive perspective.

In case of trouble, we should guard against arrogance and rashness, and we might as well look at the problem from a different angle. Maybe if you look at things and things differently, it will have an effect that you have never been able to. It certainly makes sense that everyone, everything, survives in this world.

It's up to us to appreciate it. Remember, don't give up. The words upstairs are very good, I was born to be useful!!

I didn't graduate from junior high school, I hope it will be useful to you.

1。Lose.

2。Ill-fated (tribulation).

3。was discovered.

4。Meet Bole.

5。Retire with success.

Two. Experience that others don't have.

Three. People always have strengths, give full play to their strengths, and existence is valuable.

Mentality.

3. Mentality determines success or failure.

This female paper can't afford to hurt, there is wood??

1. Math homework will cost 4a yuan, and English homework will cost 5 (a + yuan, so buy a book and spend a total of 4a + 5a + 1 = 9a + 1 yuan, and you can also get back 5-9a-1 = 4-9a yuan.

2. If each math homework book has 4 corners, it is a=

Then 4-9a = yuan.

You can also get the meta back.

If each math homework book has 4 corners, it is a=

Then 4-9a = yuan.

You can also get the meta back.

Look it up on the Internet, or gather some information.

Rises 2, 3 meters per day.

12 days up 8 meters.

On day 13, ascend another 1 meter to the treetops.

2 3 meters rise every day, 8 meters in 12 days, and another 1 meter in the day on the 13th day, so it is 13 days (daytime).

The time is divided into two sections, morning and evening, climbing one meter during the day and falling 1 3 meters at night, which is equivalent to climbing 2 3 meters a day, so it is 9 (1-1 3) =, and the whole number is 14 days.

1-1/3=2/3

9-1=8 (last trip 1m).

8 divided by 2 3 equals 12

12+1=13 (last day).

Snails climb 1-1 3 = 2 3 meters per day, it takes 9 2 3 = days.

2-3 meters per day. 9/(2/3)=。But the next day it was 8 meters. On the thirteenth day, it reached the top before it fell. So it's thirteen days.

These 6 equations are all correct, but the meaning of the equations is different.

Pick d is the same equation, but it's deformed.

c because the last 5-x should be in parentheses.

It's all right, and the sixth minus sign is a multiplier sign.
