1 Lan goes to the supermarket on foot

2 Our garden has many flowers

3 He has black hair

4 We don't have to finish the task today (not necessary => don't have to: không cần làm gì, còn must not là không được làm gì nên câu này đề cho must là sai)

5 Are there 23 students in your class?

6 Lan is not as young as Minh

>In 100 years, there’ll be too many people on Earth. So I think we have big city space. People will live space station. Children will also go to school space station. There will be special classroom for learning more about new life in space.

>Maybe children will have robots help them go to school. And turn them get up on the bed….

>The robots will be like a best friend for the children because they will talk to them and help them with any problems.

> I think children will still go to normal school and learn from their teachers. The only different is that all children will have their own computers in the classroom. There will be a lot more machines to help us learn.

As city space becomes more squeezed, we will burrow deeper and build higher with the creation of:

  • Super skyscrapers: carbon nanotubes and diamond nanothreads will help us create towering megastructures that will dwarf today’s skyscrapers
  • Earth-scrapers: just as we build up, we will also dig down – huge structures will tunnel 25 storeys deep or more
  • Underwater cities: are likely to become a reality – using the water itself to create breathable atmospheres and generating hydrogen fuel through the process

    As technology develops, we’ll see:

  • 3D printing of houses and furniture: we will be able to print exact replicas of large scale structures like houses out of local, recyclable materials
  • Stepping into home medi-pods will confirm if you really are ill, providing a digital diagnosis and supplying medicine or a remote surgeon if needed, meaning ‘pulling a sickie’ could be a thing of the past
  • And finally, we will:
  • Colonise space: first the Moon, then Mars and then far beyond into the galaxy

cutecuteo mik cần lời giải cụ thể bạn ạ

a: \(x+\dfrac{3}{9}=\dfrac{7}{6}\cdot\dfrac{2}{3}\)

=>\(x+\dfrac{1}{3}=\dfrac{14}{18}=\dfrac{7}{9}\)

=>\(x=\dfrac{7}{9}-\dfrac{1}{3}=\dfrac{7}{9}-\dfrac{3}{9}=\dfrac{4}{9}\)

b: \(x-\dfrac{2}{3}=\dfrac{1}{8}:\dfrac{5}{4}\)

=>\(x-\dfrac{2}{3}=\dfrac{1}{8}\cdot\dfrac{4}{5}=\dfrac{1}{10}\)

=>\(x=\dfrac{1}{10}+\dfrac{2}{3}=\dfrac{3+20}{30}=\dfrac{23}{30}\)

bn hãy giải chi tiết ra

\(\left(x-1\right)^2=5^2\\\Rightarrow x-1=5\\ \Rightarrow x=5+1=6\)
