tìm x

giúp mình nhé

Answer 1

Vậy kq đâu bạn ==

Đề thiếu ???

Answer 2

mình nhầm bằng 6 nhé

Answer 3

x:1+x:0.5+x:0.25+x:0.125 = ?????????????????????????????????

Answer 4

x : 1 + x : 0.5 + x : 0.25 + x : 0.125 = 6

x + x . 2 + x . 4 + x . 8 = 6

x . (1 + 2 + 4 + 8) = 6

x . 15  = 6

x       =  6:15 = 6/15

Answer 5

Trả lời:

\(x\div1+x\div0,5+x\div0,25\div0,125=6\)

\(x+x\times2+x\times4+x\times8=6\)

\(x\times\left(1+2+4+8\right)=6\)

\(x\times15=6\)

\(x=\frac{2}{5}\)

Vậy \(x=\frac{2}{5}\)

Answer 6

\(x:1+x:0,5+x:0,25+x:0,125=6\)

\(\Leftrightarrow x+x.2+x.4+x.8=6\)

\(\Leftrightarrow x.\left(1+2+4+8\right)=6\)

\(\Leftrightarrow x.15=6\)

\(\Leftrightarrow x=\frac{6}{15}\)

Vậy :............
