Là C nhé.
Vì:
Đuôi /ed/ được phát âm là /t/: Khi động từ có phát âm kết thúc là /s/, /f/, /p/, /ʃ/, /tʃ/, /k/.
Đuôi /ed/ được phát âm là /id/: Khi động từ có phát âm kết thúc là /t/ hay /d/.
Đuôi /ed/ được phát âm là /d/ với những trường hợp còn lại.
d: =>x+1/2=0 hoặc 2/3-2x=0
=>x=-1/2 hoặc x=1/3
b: \(\Leftrightarrow1-\dfrac{1}{6}+\dfrac{1}{6}-\dfrac{1}{11}+...+\dfrac{1}{5x+1}-\dfrac{1}{5x+6}=\dfrac{2010}{2011}\)
\(\Leftrightarrow1-\dfrac{1}{5x+6}=\dfrac{2010}{2011}\)
=>1/(5x+6)=1/2011
=>5x+6=2011
=>5x=2005
hay x=401
$a)a>b\\\to -a<-b\\\to -3a<-3b\\\to -3a-3<-3b-3(đpcm)\\b-2x-3<-2y-3\\\to -2x<-2y\\\to -x<-y\\\to x>y$
`c)(a-b)x<5(a-b)`
`<=>(a-b)x-5(a-b)<0`
`<=>(a-b)(x-5)<0`
Vì `x<5=>x-5<0`
`=>a-b>0`
`<=>a>b`
`d)(a-b)x<2(a-b)`
`<=>(a-b)x-2(a-b)<0`
`<=>(a-b)(x-2)<0`
Vì `x>2=>x-2>0`
`=>a-b<`
`<=>a<b`
