Take a little bit of your time!! Help me!! Thank you!!

I think it's worth it for a year to mature.

Some people try to mature themselves, but they don't succeed.

It took me at least 2 years to become a little more mature.

And what you say to go with the flow, I don't think it's necessary at all.

Why are people so tired when they are alive?

Thinking less about things won't make a difference, and thinking less about things will at least make your life easier.

Actually, your question is with yourself, no matter what the question is, after all, it is your father, I think it is much better for you to ask him than to get the answer yourself, and your father will not mislead you.

In fact, many things in life are not so smooth sailing.

Don't be serious about everything, don't be too serious about everything.

When dealing with interpersonal relationships, try not to offend anyone, maybe one day you may use it, or become a colleague or something, and leave yourself a way out for everything.

May you have a happier life in high school.

Let me guess, if there are different answers to that question, is it that one of them has a big impact on you? Is there one of these answers that makes you sad? But have you thought about it?

You've been suffering from this question for a year, and you've been worrying that the answer is going to be that bad, you've been in a state of worry, and I think, it's worse than you're going to hear that bad answer. Well, now that you've been taking on this for so long, that's enough, so let's think on the bright side. You tell yourself, you already know the answer to the question, as for what it is, it's been so long, who remembers!

Well, tomorrow is a great day, let's take a vacation and travel!

I'll send you 4 words: always think about one or two, which means to say. If there are 10 things in a person's life, there will be 8 things that are unsatisfactory, if you don't want to worry about the unsatisfactory things, then only think about those one or two things.

Remember the phrase. There is no waste in life. I spent more than half a year playing at home.

I didn't go to school either. But I've grown a lot. I've been to temples and stuff like that.

Since it exists, it must have the value of its existence. To be honest, I only read the last sentence of your question. But that should be fine. )

Chen Chen's speed is x, and the speed of ice cold is y.

25x+25y=400

3y=5x solution. x=

The velocity of A is x, and the velocity of B is y.

25x+25y=400

3y=5x solution. x=

v Binghan + v Chen Chen = 400 25 = 8m s

v Bing Han * 3s = v Chen Chen * (2 + 3) s

v Chen Chen = 3m s

v ice chill = 5 m s

Hello, is it useful to help you do it now, or I'll help you do a question first, and I'll help you do it if it's useful. But after looking at your own Mingqiao, you have to ponder the Lahuai Zhao, which is actually quite easy to understand 1Untie; Substituting the two points a and b into the function y=ax2-5x+c respectively gives 0=a-5+c from a-5+c=0 a+c=5 a=5-c 0=16a-20+c

Substituting 16 5-16c-20+c=o. 0=16a-20+c ② 80-16c-20+c=o . 60-15c=0 .

Then -15c=-60 c=4Substituting c=4 into a=5-c yields a=1. So its analytic formula is, y=x2-5x+4

One, 1, A+8

4. The reservoir has two inlet pipes, A and C, and B. D two drainage pipes, to fill a pool of water, a single opening A takes 3 hours, a single opening C takes 5 hours, to drain a pool of water, a single opening B takes 4 hours, a single opening Ding takes 6 hours, now there is a mountain guess 1 6 pool of water in the pool, if press A. Ethyl-C.

Ding in the order of circulating each tube, each tube open for 1 hour, ask how long after the pool water begins to benefit out of the pool?

Cycle each tube in the order of A, B, C, D, each tube is open for 1 hour, a cycle is 4 hours, and a total of 7 60 water is in.

There are 1 6 pools of water in the pool, and it is impossible to fill the pool in the process of a cycle, and there is water 1 6 + 7 60 in the pool after a cycle.

Clause. The second, third, fourth, and fifth cycles should also not fill the pool during and after the cycle. But when the fifth cycle is over, there is already water in the pool: 1 6 + 7 60 * 5 = 45 60 = 3 4, and there is still a difference of 1 4.

At the beginning of the sixth cycle, when A pumped water: 1 4 1 3 = 3 4 hours, the pool was just full.

So the time required is: wide pants 4 5 + 3 4 = 20 and 3 4 (hours).
