a) 89,42 + ( 21,15 + 16,471 ) = 89,42 + 37,621 = 127,041

b) ( 135,8 + 69,07 ) + 52,18 = 204,87 + 52,18 = 257,05

c) ( 89,42 + 21,15 ) + 16,471 = 110,57 + 16,271 = 127,041

d) 135,8 + ( 69,07 + 52,18 ) = 135,8 + 121,25 = 257,05

hãy viết 4 giá trị của x sao cho :

6,01 < x < 6,02

TL:

\(x\in\left\{6,012;6,011;6,013;6,014;...\right\}\)

6,01 < x < 6,02.

\(\Rightarrow\)x = 6,011; 6,012; 6,015; 6,019.

Watching television is my favourite activities I use to do in my free time. I love watching sports programs on Saturday mornings and cartoons on Sunday afternoons. I usually watch movie during all days of week after I have completed my homework at school. At night, I especially enjoy watching situation comedies and movies. If I have a huge number of  school work, I try to manage my schedule so that I will able to see at least 1 of my favorite TV shows. Watching TV isn’t the only indoor activity that I can do in my free time. I also have some other favorite activities  such as going shopping with my mother or friends and making paper flowers. However, when I have free time, I spend a lot of time on watching TV than other activities. Watching TV can support me not only relax but also build my knowledge about the open world.

Most of us have individual preferences. Collecting certain objects such as: coin, skers, shoes, etc. is one of the most popular hobbies.

My hobby is collecting skers. It is also the most popular hobbies among children in my neighborhood. Children are interested in collecting skers because it is not an expensive hobby. I started this pastime since I was four years old. My hobby began through the influence of my best friend, Quan. One day, when I was playing in his house, he showed me his colorful sker albums with full of his pride. I was amazed to see so many impressed skers of all shapes and sizes. He gave me a few pieces from his collection and told me about his interesting story about his passion. I was taken inspiration from him and my interest in skers started from that day.

I kept my first set of skers in a scrapbook but my subsequent collections were kept in beautiful boxes because I think some of the skers could not be removed easily when pasted onto the albums. Keeping the skers in boxes helps me exchange some of my skers with my friends conveniently without damaging them.

Ever since my family members came to know of my interest in skers, they will buy skers for me whenever they come across nice ones. I love those skers from my cousin who is an overseas student in London. He bought them for me wherever he visited around the world. Some of the unique ones were from his classmates who come from many different countries.

During my free time, I will bring out all my lovely collections, lay them on the ground and admire them. I really enjoy doing this as it will help me recall who gave them, where and when I got them.

Some of my friends are jealous of my collections as I will not exchange my unique skers with them. Till now, I still share my collections with my best friend – Quan. I must really thank Quan for his little gift which started my hobby.

\(x-7,6+12,15=16,72+9,3\)

\(x-7,6+12,15=26,02\)

\(x-7,6=26,02-12,15\)

\(x-7,6=13,87\)

\(x=13,87+7,6\)

\(x=21,47\)

(x-7,6+12,75)=16,72+9,3

(x-7,6+12,75)=26,02

x-7,6            =26,02-12,75

x-7,6            =13,27

x                  =13,27+7,6
