Question

tim x

100-(x:5+3/2)=80

Answer 1

\(100-\left(\frac{x}{5}+\frac{3}{2}\right)=80\)

\(\frac{x}{5}+\frac{3}{2}=20\)

\(\frac{x}{5}=18,5\)

\(x=92,5\)

Answer 2

x:5+3/2= 100-80

x:5+3/2=20

x:5=20-3/2

x:5=37/2

x= 37/2x5

x=185/2

Answer 3

100 - ( x : 5 + \(\frac{3}{2}\)) = 80

         ( x : 5 + \(\frac{3}{2}\)) = 100 - 80

         ( x : 5 + \(\frac{3}{2}\)) = 20

         ( x : 5)               = 20 - \(\frac{3}{2}\)

         ( x : 5)               = 18,5

           x                      = 18,5 x 5

          x                       = 92,5

Vậy x = 92,5

Answer 4

100-(x:5+3/2)=80

x:5+3/2=100-80

x:5+3/2=20

x:5=20-3/2

x:5=37/2

x=37/2x5

x=185/2

Vậy x=185/2

Answer 5

Tìm x : 

100 - ( x : 5 + 3/2 ) = 80 

x : 5 + 3/2 = 100 - 80 

x : 5 + 3/2 = 20 

x : 5 = 20 - 3/2 

x : 5 = 37/2

x = 37/2 × 5 

x = 185/2 

Vậy x = 185/2

Answer 6

\(100-\left(x\div5+\frac{3}{2}\right)=80\)

\(\Rightarrow x\div5+\frac{3}{2}=100-80\)

\(\Rightarrow x\div5+\frac{3}{2}=20\)

\(\Rightarrow x\div5=20-\frac{3}{2}\)

\(\Rightarrow x\div5=\frac{37}{2}\)

\(\Rightarrow x=\frac{37}{2}\times5\)

\(\Rightarrow x=\frac{185}{2}\)

Vậy \(x=\frac{185}{2}\)

Answer 7

   

 \(100-\left(x:5+\frac{3}{2}\right)=8\)

\(\Leftrightarrow x:5+\frac{3}{2}=100-8\)

\(\Leftrightarrow x:5+\frac{3}{2}=92\)

\(\Leftrightarrow x:5=92-\frac{3}{2}\)

\(\Leftrightarrow x:5=\)?    ( Bạn dùng máy tính mà tính nhé)

\(\Rightarrow x=\)?
