8. My sister is a student. -> What does your sister do?
9. I go to bed early because I feel tired. -> Why do you go bed early?
10. She is travelling by car.-> How is she travelling?
0,2x-2/3(x+1)=1/3
<=>0,2x-2/3x-2/3=1/3
<=>-7/15x=1
<=>x=-15/7
Vậy..............
Hok tốt
\(0,2x-\frac{2}{3}\left(x+1\right)=\frac{1}{3}\)
\(\frac{1}{5}x-\frac{2}{3}x+\frac{2}{3}=\frac{1}{3}\)
\(\left(\frac{1}{5}-\frac{2}{3}\right)x=-\frac{1}{3}\)
\(-\frac{7}{15}x=-\frac{1}{3}\)
\(x=\frac{5}{7}\)
=1/3-1/4+1/4-1/5+...+1/2005-1/2006
=1/3-1/2006
=2006/6018-3/6018
=2003/6018
Nếu đúng thì giữ lời hứa nhé
a) \(\frac{-7}{9}và\frac{3}{-8}\)
Ta có: \(\frac{-7}{9}=\frac{-56}{72}\)
\(\frac{3}{-8}=\frac{-3}{8}=\frac{-21}{72}\)
\(Vì\frac{-56}{72}< \frac{-21}{72}nên\frac{-7}{9}< \frac{3}{-8}\)
b)\(\frac{209}{310}và\frac{-718}{599}\)
Ta có: \(\frac{209}{310}>0\)
\(\frac{-718}{599}< 0\)
\(Vì\frac{209}{310}>0và\frac{-718}{599}< 0nên\frac{209}{310}>\frac{-718}{599}\)
Nếu ^ là dấu nhân thì kết quả là :A = 19699,9 , B = 19911 .
Vậy A < B .
999999999999999999999999999999 > 99999999999999999999999999999
lớn hơn nha>
