R A nh rảnh quớ bn ơi......rảnh đi hok đê.......Ai fan Noo tk mk ha.....I Love You forever, Noo.....
My neiborhood is not big, but it has a nice view. But, some year recently, people often do not take rubbish into recycle bins, walk on the grass, use more dirty energy, noise pollution,.... So I dislike something much. Althought my neighbor is so dirty, peole here improve themselevs. I like my neighborhood because it's my homeland, the peole here so friendly, there are a lot of parks, supermarkets, schools,... here.
I like living in the countryside because of some reasons. Environmentally speaking, it is a peaceful place. The air is fresh. The space is quiet. We can enjoy healthy natural conditions without
worrying much about environmental pollution.
As for social security, the countryside is a safer place than a city. While urban security situation is always complicated with all kinds of crimes, rural areas are much more secure because most of countrymen are friendly and ready to help one another.
Moreover, rural life is also easier that in cities. People in cities are easy to get stressed because of pollution, job pressures, competitions, etc ... On the contrary, those bad things
are very rare in the countryside. To sum up, except income matters, the countryside is a better residence than cities.
Gọi số cần tìm là x, theo đề bài, ta có:
2017 x 101 - 201,7 - x = 201,7 x 500 x 2
= 203 717 - 201,7 - x = 201,7 x (500 x 2)
= 203 515,3 - x = 201,7 x 1000
= 203 515,3 - x = 201700
= x = 203 515,3 - 201700
= x = 1815,3
⇒ x = 201,7 x 9
⇒ Vậy số cần tìm là 1815,3 hoặc 201,7 x 9.
