`250:(x-8)=25`

`=> x-8=250:25`

`=> x-8=10`

`=> x=10+8`

`=> x=18`

250 : ( x - 8 ) = 25

x - 8 = 250 : 25

x - 8 = 10

x = 10 + 8

x = 18

vậy x = 18

$250:(x-8)=25$

$=>x-8=250:25$

$=>x-8=10$

$=>x=10+8$

$=>x=18$

ai biết ko ?

a=25x(725+250+25)

  =25x1000

  =25000

cái b tôi ko biết'

       \(250\div5\left(x+1\right)=25.\)

<=> \(5x+5=10.\)

<=> \(x=1.\)

Vậy x = 1.

101 \(\times\) 9,4 - 9,4 + 25 \(\times\) \(\dfrac{2,4}{250\%}\) \(\times\) 125% \(\times\) 32

= 9,4 \(\times\)100 + 25 \(\times\) \(\dfrac{24}{25}\) \(\times\) 10 \(\times\) 4

= 94 \(\times\)10 + 24 \(\times\) 4 \(\times\) 10

= 10 \(\times\) ( 94 + 96)

= 10 \(\times\) 190

= 1900 

     250 + 25 X 4  

=250 +  100

= 350

k M NHA

250 + 25 x 4 

= 250 + 100

= 350

k mình nha!

= 250 + 100

=350.

bạn nào thấy đúng thì kb nha
