\(x\) - (10 - \(x\)) = \(x\) - 22

\(x\) - 10 + \(x\) = \(x\) - 22

2\(x\) - 10 = \(x\) - 22

2\(x\) - \(x\)  = -22 + 10

\(x\)         = - 12

Ta có sơ đồ sau khi bán

Chương trình TV mà em yêu thích:

I very like watching cartoons. And of all the film I have seen, “Grave of the fireflies” is one in the cartoons which I like most. In Vietnamese it’s called is “Căn hầm đom đóm” or “Mộ đom đóm”. It’s a tragic story about two childents in the war. It’s made from Japan by Ghibli studio, directed and written by Takahata Isao. It is based on a nover of Nosaka Akiyuki. It’s written as a apologize to his sister. With Japanese, this film is understaned as a fable about the respect. Film is been in historical background at the end of the seconds world war from Japan. Film tells a painful story but moving to brothers sentiment of two orphaneds : Seita and Setsuko. They lost mother after a fierce bombing of American air force to Kobe city while their father combat for Japanese navy. So Seita and Setsuko must to struggle to exist between the famine and the resistance to merciless of surrounding people (that have their kinship). They have to live in a shelter-pit and often eat frogs and lizards. At the end, Setsuko have to die for hunger, pictures depict painfulness and the death of little girl can be considered as the most mournful film pictures in the cartoon Japan history. When everybody, who had seen this film are asked, most of them said they cried, and that have me

Về vấn đề môi trường:

Enviroment is the most important thing for our life. Enviroment is the air we breath, the water we drink and is everything we need for our life. But now that most important thing for our life is being polluted and by many different ways. This pollution affects the health of living things. Air is damaged by car and lorry fumes, and power stations create acid rain which destroys entire forests and lakes. When fossil fuels i.e. oil, gas and coal are burned to provide energy for lighting, cooking etc. they form polluting gases. Not only on land but also in the sea, oils spills pollute sea water and kill marine life; chemical waste from factories and sewage works, and artificial fertilisers from farmland, pollute river water, killing wildlife and spreading disease. Everything is being caused by human’s existence. Humans create such a lot of rubbish! Each household produces about 1 tonne of rubbish every year! Most of this is taken away by dustmen and buried in enormous landfill sites or burned in incinerators - both of these actions can be dangerous for the environment.

But only we can change it and solve it. Pollution can be prevented by thing we do everyday. First we can use recycled paper to help save trees. Second try to avoid buying plastic. It's hard to recycle. One way to cut down on plastic is to refuse to use carrier bags. If we can’t avoid buying plastic bags, we should use re-use plastic bags over and over again, until they wear out. Finally we should take your old clothes to charity shops, some are sold. To protect environment we also have to save energy. Use less energy by switching off lights when rooms are not in use, not wasting water; don’t forget to switch off all electric things when they are not in use, use a bicycle or walk instead of using a car for short trips we can save energy, keep clean atmosphere and keep healthy life. Lighting accounts for 10 percent to 15 percent of the electricity bill. However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb and we still trying to invent the new thing to save money as well as conserve the Earth’s resources.

Keep clean environment isn’t only all ways are mentioned before but also to protect natural resources. That is the way to conserver wild life. First we need to conserve the old forest, rainforest, build more safari and national park, and plant more trees to make place to live for wild animals. Second we need to prohibit hunters who hunt animals too many out of the law allowance.

Finally, we now know that enviroment is the most important thing for life and we know how to protect and use it scientifically. Everyday we invent and find more and more way to protect enviroment. I hope that in the future the earth will be cleaner.
