Among my favourite sports and hobbies, I like swimming the best for several reasons. Firstly, I think playing in the water could bring great joy. It also helps reduce stress and I always feel refreshed and relaxed after swimming for about half an hour. Secondly, swimming is an excellent way to keep myself fit and healthy. It helps build up my muscle strength and prevent many heart and lung diseases. Finally, besides being a great sport, swimming is also an important survival skill, because without knowing how to swim well, it could be dangerous if there is a flood, or simply if we want to play near bodies of water. Many of such accidents have occured to teenagers lately. In conclusion, swimming will always be my preferred hobby because it is not only healthy and fun but also a life-saving skill.

My favorite sport is badminton. I like playing it because I think it is a good sport. Every sport will make people feel hot and uncomfortable, but when you play badminton, you will be comfortable because in the badminton court, there are many air-conditioners.
I usually play badminton on Sunday. I always play with my friend, Linh. She is good at badminton. But I am not very good at this sport so when we play badminton, she hits the ball on my both sides. She makes me run and run, and I feel very tired. Sometimes I must jump high to hit the ball to the opposite side.
Although this makes me tired, I still always practice because I will be healthier and fitter than before. Anyway, I think badminton is the best sport.

In my freetime, I love to dance. When I was a little girl I danced all the time. My mother put me in dance school when I was 3 years old. My first dance dress was pink and it was love a ballet dress. Our dance group’s firts show was when we were 5 years old. We looked like pinguis. In 9 years we have had a lot of dance shows. I have danced for 9 years in the same dance company. But now everyone has joined other dance groups.
When I dance I forget everything else and I focus only on dancing. It was relaxing and it makes me happy. I like to take care of my body and dancing enhances your condition.
But now when I’m in High school I do not have time to dance. It’s so sad. I miss dancing . I hope that I have time to dance again day.

a) | x - 5 | < 5

=> \(\left[\begin{matrix}x - 5\:=5\\x\:-5\:=-5\end{matrix}\right.\)

=> \(\left[\begin{matrix}x=10\\x\:=0\end{matrix}\right.\)

a) |3 - x | = 7

=> 3 - x = 7

3 - x = - 7

=> x = - 4

x = 10

Ta có hình vẽ:

Thùng 1: |---|---|---|---|---|

Thùng 2: |---|---|---|

Hiệu số phần bằng nhau là:

5 - 3 = 2 ( phần )

Thùng 1 có số dầu là:

180 : 2 x 5 = 450 ( l )

Thùng 2 có số dầu là:

450 - 180 = 270 ( l )

Đáp số: Thùng 1: 450 l

Thùng 2: 270 l
