1.B -> collecting

2. C -> visit

3. A-> play

4.C -> climbing

5. D -> postcard

x =( \(\dfrac{3}{7}\)) ⁷ : (\(\dfrac{3}{5}\))⁵

Sau đó tự tính nhé !

1. Those men are very tall.

=> What those men very tall ?

2. He has a lovely garden.

=> What a lovely garden he has ?

Còn câu 3 bạn cần đưa ra phần được gạch chân thì mới làm được nhé !

Chúc bạn học tốt !

[ (\(\dfrac{4}{3}\))^-2 . (\(\dfrac{3}{4}\))⁴] : (\(\dfrac{3}{2}\))⁵

^{=> = (\(\dfrac{9}{16}\)}. \(\dfrac{81}{256}\)) : \(\dfrac{243}{32}\)

=> = \(\dfrac{729}{4096}\): \(\dfrac{243}{32}\)

=> = \(\dfrac{96}{409}\)

Chúc bạn học tốt !

Đăng câu hỏi lên mình làm nhé !

1. a.|x - 1 |= x -1

\(\left[{}\begin{matrix}x-1=x-1\\x-1=-x+1\end{matrix}\right.\)

=>\(\left[{}\begin{matrix}x=0\\2x=2\end{matrix}\right.\)

=>\(\left[{}\begin{matrix}x=0\\x=1\end{matrix}\right.\)

Chúc bạn học tốt !

1. I am the best student in her class.

2.

7. They are studying English at the moment.

P/S : Mấy câu mình bỏ trống ,mình không rõ , hình như sai đề !

Chúc bạn học tốt !

Câu 2 : ( x - \(\dfrac{1}{2}\)) : \(\dfrac{1}{3}\)+ \(\dfrac{5}{7}\) = 9\(\dfrac{5}{7}\)

=> ( x - \(\dfrac{1}{2}\)) : \(\dfrac{1}{3}\)= 9

=> x - \(\dfrac{1}{2}\)= 9 . \(\dfrac{1}{3}\)

=> x - \(\dfrac{1}{2}\)= 3

=> x = 3 + \(\dfrac{1}{2}\)

=> x = \(\dfrac{7}{2}\)

Chúc bạn học tốt !

Câu 1 :

\(\dfrac{5}{7}\)+ \(\dfrac{2}{3}\). x =\(\dfrac{3}{10}\)

=> \(\dfrac{2}{3}\).x = \(\dfrac{3}{10}\) - \(\dfrac{5}{7}\)

=> \(\dfrac{2}{3}\). x = \(\dfrac{-29}{70}\)

=> x = \(\dfrac{-29}{70}\): \(\dfrac{2}{3}\)

=> x = \(\dfrac{-87}{140}\)

( 3x - \(\dfrac{1}{2}\))2 = \(\dfrac{4}{9}\)

=> 3x - \(\dfrac{1}{2}\)= \(\dfrac{4}{9}\): 2

=> 3x - \(\dfrac{1}{2}\)= \(\dfrac{2}{9}\)

=> 3x = \(\dfrac{2}{9}\)+ \(\dfrac{1}{2}\)

=> 3x= \(\dfrac{13}{18}\)

=> x = \(\dfrac{13}{54}\)
