Question

X : 25% + X : 0,5 + X × 5 - X = 270

  Làm giúp mk nhé 

Answer 1

\(x:25\%+x:0,5+x\cdot5=270\)

\(x\cdot4+x\cdot2+x\cdot5=270\)

\(x\cdot\left(4+2+5\right)=270\)

\(x\cdot11=270\)

\(x=\dfrac{270}{11}\)

Answer 2

X : 25% + X : 0,5 + X x 5 - X = 270

X : \(\dfrac{1}{4}\) + X : \(\dfrac{1}{2}\) + X x 5 -X =270

X x 4 +X x 2 +X x 5 -X = 270

X x ( 4+ 2+ 5 -1 ) = 270

x x 10 = 270

X         = 270 : 10

X          = 27

Answer 3

X x 4 + X x 2 +X x 5 - X= 270

X x (4+2+5)-x =270

X x 11- X x1= 270

X x (11-1) =270

X x10=270

       X=270 :10

         X=27

Answer 4

$x:25\%+x:0,5+x\cdot 5=270$

$x\cdot 4+x\cdot 2+x\cdot 5=270$

$x\cdot \left(4+2+5\right)=270$

$x\cdot 11=270$
