525 : x + 700 : x = 7

( 525 + 700 ) : x = 7

1225 : x = 7

x = 1225 : 7

x = 175

Nhớ tick cho mik nha !!!

525:x+700:x=7

(525+700):x=7

1225:x=7

x=1225:7

x=175

tick nha

525 : x + 700 : x = 7

( 525 + 700 ) : x = 7

1225 : x = 7

x = 1225 : 7

x = 175

Bấm đúng cho mik nha !!!

X : 525 + 700 : X = 7

<=> ( 525 + 700 ) : X = 7

<=> 1225 :x = 7

<=> x= 1225/7

<=> x=175

X:525+700:X=7

(525+700):x=7

1225:x=7

x=1225:7

x=175

525:x+700:x=7

(525+700):x=7

1225:x=7

x=1225:7

x=175

\(\frac{525}{x}+\frac{700}{x}=7\Rightarrow\frac{1}{x}\left(525+700\right)=7\Rightarrow\frac{1}{x}=\frac{1}{175}\Rightarrow x=175\)

a) 4 735 + 15 > 4 735 + 10

b) 524 – 10 < 525 – 10

c) 4 735 – 15 < 4 735 – 10

d) 7 700 + 2 000 = 6 700 + 3 000

525 + 525 x 3 + 998 x 525 - 525 x 2

= 525 x 4 + 523950 - 1050

= 2100 + 522900

= 525000

525 + 525 x 3 + 998 x 525 - 525 x 2

= 525 x 1 + 525 x 3 + 998 x 525 - 525 x 2

= 525 x (1 + 3 + 998 - 2)

=525 x 1000

=525000

\(\Leftrightarrow x\times\left(3+7\right)=700\\ \Leftrightarrow x\times10=700\\ \Leftrightarrow x=700:10\\ \Leftrightarrow x=70\)

\(x\times\)(3 + 7) = 700

\(x\times\)   10       = 700

\(x=700:10=70\)

525 x 341 + 252 x 659

= 525 x ( 341 + 659 )

= 525 x 1000

= 525000

TK nhé

525 x 341 + 525 x 659

= 525 x ( 341 + 659 )

= 525 x 1000

= 525000
