x + x : 0,25 + x :0,5 + x : 0,125 = 0,45

tìm x

Answer 1

`x+x:0,25+x:0,5+x:0,125=0,45`

`x+x xx4+x xx2+x xx8=0,45`

`x xx(1+4+2+8)=0,45`

`x xx15=0,45`

`x=0,45:15=0,03`

Answer 2

=>x+4x+2x+8x=0,45

=>15x=0,45

hay x=0,03

Answer 3

0,03 nha

Answer 4

\(x+x\times4+x\times2+x\times8=0,45\)

\(x\times\left(2+4+8+1\right)=0,45\)

\(x\times15=0,45\)

\(x=0,45;15\)

\(x=0,03\)

Answer 5

=>x+4x+2x+8x=0,45
