1000 k cho mk nhé rồi mk đặt đại câu hỏi bạn trả lời mk k lại mk nói thật đó

548+452=1 000

548+452=1000

484+x = -632 + (-548)

484+x = -1180

x= -1180 - 484

x= -1664

484 + x = -632 + (-548)

484 + x = -1180

x = -1180 - 484

x = - 1664

484+x=-632+(-548)

484+x=-1180

x=-1180-484

x=-1664

Ta có:

  \(548⋮a\)

  \(638⋮a\)

\(\Rightarrow a=ƯC\left(548;638\right)\)

Ta có:\(548=2^2.137\)

         \(638=2.11.29\)

\(\RightarrowƯCLN\left(548;638\right)=2\)

\(\RightarrowƯC\left(548;638\right)=Ư\left(2\right)=\left\{1;2\right\}\)

Vậy a=1;2

đề đâu bạn

( - 452 ) + 395 + ( -548 ) + 605

= - ( 452 + 548 ) + ( 395 + 605)

= -1000 + 1000

=0

HOK TỐT

Ta có : \(\left(-452\right)+395+\left(-548\right)+605\)

            \(=\left[\left(-452\right)+\left(548\right)\right]+\left(395+605\right)\)

           \(=\left(-1000\right)+1000\)

             \(=0\)

STUDY WELL !

( - 452 ) + 395 + ( - 548 ) + 605

= [ ( - 452 ) + ( - 548 )] + ( 395 + 605 )

= - 1000 +1000

= 0

Đây là tìm x chứ?

\(\Rightarrow\left(-484+x\right)=\left(-584\right)-\left(-632\right)\\ \Rightarrow\left(-484+x\right)=48\\ \Rightarrow x=48-\left(-484\right)\\ \Rightarrow x=532\)

=>-548+484-x=-632

=>x+64=632

hay x=568

452 - (-673 + 548 - 123) + (-327)

= 452 + 248 - 327

= 700 - 327

= 373

452-(-673+548-123)+(-327)

=452+673-548+123-327

=373

= 452+248-327

=    700    -327

=          373

\(\left(x+175\right):x+30=548\)

\(\Rightarrow\left(x+175\right):x=518\)

\(\Rightarrow x+175=518x\)

\(\Rightarrow517x=175\)

\(\Rightarrow x=\frac{175}{517}\)

=>( X+175) : X= 548-30=518

=>X:X+175:X=518

=>1+175 : X=518

=>175 :X=517

=>X=175:517

=>X=175/517

  Vậy X=175/517
