hello you

Hello everyone!

Cuong co so vien keo la:

         ( 24+28):3=14( vien keo)

                         dap so: 14 vien keo.

4800 : ( X x 16 ) = 25

X x 16 = 4800 : 25

X x 16 = 192

       X = 192 : 16

       X = 12

2009 : ( 71 : x ) = 2009

71 : x = 2009 : 2009

71 : x = 1

       x = 71 : 1

       x = 71

4800 : ( x . 16 ) = 25

x . 16 = 4800 : 25 

x . 16 = 192

x = 192 : 16

x = 12

 I usually get up early in the morning. After brushing my teeth, having breakfast, I go to school. My school is not very far from my house, so I always go by bike. It's very interesting to travel by bike. it helps keep the environment clean. My classes always finish at 11:15. I and my friends have lunch at school. Our lunch time is about 2 hours. Our practising lessons begin at 2:10 pm. We review and practise what we have learnt in the morning, we do our exercises and do labour work in the school garden. It's always interesting time for work and passion. We also have short break for relax in the afternoon. Our schooling of the afternoon often ends at 3:00 o'clock. We come back home and have dinner with family at home. It's a great time to stay with the family after a hard working day. In the evening, we usually watch TV, or listen to music. Sometimes we go to the cinemar. It's usually at weekend. Time in the family is always pleasure but I also love my school and my friends very much.

2015:(65:x):2015

Ta có:2015:(65:65):2015 mà x = 65 vì chỉ có 65:65=1 để 2015:1:2015 mới thõa mãn yêu cầu đề bài

Để 2015:(65:65):2015=1 (thõa mãn)

Vậy x=65 và giá trị thõa mãn đề bài là 1
