\(x\times4\times x=55,35\)

\(x\times x=55,35:4\)

\(x\times x=13,8375\)

\(\Rightarrow x=3,719879....\)

x * 4 + 0 , 5 * x = 55 , 35

x * ( 4 + 0 , 5 )  = 55 , 35 

x * 4, 5             = 55 , 35 

      x                = 55 , 35 : 4 , 5 

      x                = 12 , 3 

Vậy x                = 12 , 3 

\(4x+\frac{1}{2}x=55,35.\)

\(\Leftrightarrow\left(4+\frac{1}{2}\right)x=55,35.\)

\(\Leftrightarrow4,5x=55,35\)

\(\Leftrightarrow x=12,3\)

hộ mình với mình đang cần gấp

\(x\cdot4+\frac{1}{2}\cdot x=55,35\)

\(x\cdot\left(4+\frac{1}{2}\right)=55,35\)

\(x\cdot\frac{9}{2}=55,35\)

\(x=12,3\)

x*4+1/2*x=55,35

=x*(4+1/2)=55,35

=x*4,5=55,35

=55,35:4,5

=12,3

123/10 hoặc 12,3

a/ x = 6

b/ x = 12,3

Bài 1: 0,01m³ < 1,99m³

Bài 2: Tìm \(x\):

\(x\)x 4 + \(\frac{1}{2}\)x \(x\)= 55,35

\(x\)x (4 + \(\frac{1}{2}\)) = 55,35

\(x\)x \(\frac{9}{2}\)= 55,35

\(x\)= 55,35 : \(\frac{9}{2}\)

\(x\)= 249,075

1,

\(0,01m^3=\frac{1}{100}m^3\); vậy  \(\frac{1}{100}m^3< \frac{1}{99}m^3\)

2, Lời giải

\(x\cdot4+\frac{1}{2}\cdot x=55,35\)

\(\Rightarrow x\cdot\left(4+\frac{1}{2}\right)=55,35\)

\(\Rightarrow x\cdot4\frac{1}{2}=55.35\)

\(\Rightarrow x\cdot4,5=55,35\)

            \(x=55,35:4,5\)

            \(x=12,3\)

`!`

`x xx 4 +1/2 xx x=55,35`

`=> x xx ( 4+1/2) =55,35`

`=  x xx 9/2=55,35`

`=>x= 55,35 : 9/2`

`=>x= 3,075`
