Answer 2

`a)274 xx x-265 xx x=5130`

`x xx ( 274 - 256 )  = 5130 `

`x xx 18                  = 5130 `

`x                          = 5130 : 18 `

`x                          = 285 `

`b)100−x÷24=65`

`⇒x÷24=100−65`

`x÷24=35`

`x=35xx24`

`x=840`

`c)x:11=282:8`

`x:11=35,25`

`x=35,25xx11`

`x=387,75`

`d)x:304=127xx4`

`x:304=508`

`x=304xx508`

`x=154432`

Answer 3

Answer 4

\(a,x\left(274-265\right)=5130\\ 9x=5130\\ x=570\\ b,100-x:24=65\\ -x:24=-35\\ x=840\)

\(c,x:11=35,25\\ x=387,75\\ d,x:304=508\\ x=154432\)

Answer 5

`274 xx x - 265 xx x = 5130`

` x xx ( 274 - 265) = 5130`

`x xx 9 = 5130`

`x = 5130 : 9`

`x = 570`

____________________

`100 - x : 24 = 65`

`x : 24 = 100 - 65`

`x : 24 = 35`

`x = 35 xx 24`

`x = 840`

_____________________

` x : 11 =282 : 8`

`x : 11=35,25`

`x= 35,25 xx 11`

`x = 387,75`

_________________________

` x : 304 = 127 xx 4`

`x : 304 = 508`

`x = 508 xx 304`

`x= 154432`

Answer 6

`a)274xx x-265x xx=5130`

`9xx x =5130`

`x=5130:9`

`x=570`

`b)100-x:24=65`

`x:24=100-65`

`x:24=35`

`x=35xx24`

`x=840`

`c)x:11=282:8`

`x=282:8 xx11`

`x=1551/4`

`d)x:304=127xx4`

`x:304=508`

`x=508xx304`

`x=154432`

Answer 7

b-

= > x:24 = 100 - 65 = 35

=> x = 35 nhân 24 = 840
