Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home? We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do these help us to save money but also they work effectively.
In addition, we should frequently check electrical equipments in our home in order to fix opportunely. In summary, we need to save energy so that energy isn't run out and continues to serve human's life.
As you know, energy is very important for our life and it is being run out more and more. I think we need to save energy because nobody can live without energy. Firstly, using less energy has lots of benefits – we can save money and help the environment. Energy production requires precious natural resources, such as coal, oil or gas. Therefore, using less energy will help us maintain these resources and make them last longer into the future. Secondly, we can change our means of transportation, if possible, we can walk or ride bicycle instead of taking the car. Finally, we save electricity by turning off all the appliances before going out or going to bed. Another way is to use energy saving light bulbs. Our electricity bill will be reduced by using this way. In short, saving energy is very necessary for our life in modern society. I think we should use them carefully because all of them are limited and they will be exhausted in the future.

1, The flower is watered by my father everyday.

\(\left(\dfrac{1}{4}+35\%+0,65+75\%\right)\times\left(1\dfrac{6}{9}+4\dfrac{8}{24}\right)\)
\(=\left(0,25+0,35+0,65+0,75\right)\times\left(1+\dfrac{2}{3}+4+\dfrac{1}{3}\right)\)
\(=2\times6\)
\(=12\)
\(\left(\dfrac{1}{4}+35\%+0,65+75\%\right)\times\left(1\dfrac{6}{9}+4\dfrac{8}{24}\right)\)
\(=\left(\dfrac{1}{4}+\dfrac{7}{20}+\dfrac{65}{100}+\dfrac{3}{4}\right)\times\left(\dfrac{15}{9}+\dfrac{13}{3}\right)\)
\(=\left(\dfrac{5}{20}+\dfrac{7}{20}+\dfrac{13}{20}+\dfrac{15}{20}\right)\times6\)
\(=\left[\left(\dfrac{15}{20}+\dfrac{5}{20}\right)+\left(\dfrac{7}{20}+\dfrac{13}{20}\right)\right]\times6\)
\(=2\times6\)
\(=12\)
\(110-3\times\left(8+x\right)=1\)
\(3\times\left(8+x\right)=110-1\)
\(3\times\left(8+x\right)=109\)
\(8+x=\dfrac{109}{3}\)
\(x=\dfrac{109}{3}-8\)
\(x=\dfrac{85}{3}\)
Chúc bạn học tốt
abc,d-a,bcd=562,122
=> 0 - d=2 nên d phải bằng 8 (nhớ 1)
0-c-1(nhớ)=2 nên c=7
d-b-1(nhớ)=1 hay 8-b-1(nhớ)=1 nên b = 6
c-a=2 hay 7-a=2 nên a = 5
vậy a=5;b=6;c=7;d=8
thử lại 567,8-5,678=562,122
