Question

X x 95 + X : 0.2 = 25

tìm X

Answer 1

\(x.95+x.0,2=25\)

\(=x.95+x.\frac{5}{1}=25\)

 \(x.\left(95+\frac{5}{1}\right)=25\)

\(x.100=25\)

\(x=25:100\)

\(x=0,25=\frac{1}{4}\)

Answer 2

X x 95 + X : 0,2 = 25

X x 95 + X x 5 = 25

X x ( 95 + 5 ) = 25

X x 100 = 25

X = 25 : 100

X = 0,25

Answer 3

x=0,25

Answer 4

x=0,25 chac 100% luon

Answer 5

\(x\times95+x\div0,2=25\)

\(x\times95+x\div\frac{1}{5}=25\)

\(x\times\left(95+5\right)=25\)

\(x\times100=25\)

\(x=25\div100\)

\(x=\frac{1}{4}\)

Vậy \(x=\frac{1}{4}\)

Answer 6

\(x.95+x:0,2=25\)

\(\Rightarrow x.95+x:\frac{2}{10}=25\)

\(\Rightarrow x.95+x.5=25\)

\(\Rightarrow x.\left(95+5\right)=25\)

\(\Rightarrow x.100=25\)

\(\Rightarrow x=25:100\)

\(\Rightarrow x=0,25\)

Vậy x = 0,25

Answer 7

\(x\times95+x:0,2=25\)

\(x\times95+x\times5=25\)

\(x\times\left(95+5\right)=25\)

\(x\times100=25\)

\(x=25:100\)

\(x=0,25\text{ hoặc }x=\frac{1}{4}\)

Answer 8

Xx95+Xx5=25

=)Xx(95+5)=25

Xx100=25

X=25:100

X=0,25

k mk nha

Answer 9

X x 95 + X x 1/5 = 25

X x (95 + 1/5) = 25

X x 476/5 = 25

X = 25 : 476/5

X = 125/476

Answer 10

\(x\times95+x:0,2=25\)

\(\Leftrightarrow x\times95+x\times5=25\)

\(\Leftrightarrow x\left(95+5\right)=25\)

\(\Leftrightarrow x\times100=25\)

\(\Leftrightarrow x=0,25\)
