\(x\cdot4+\frac{1}{2}\cdot x=55,35\)
\(x\cdot\left(4+\frac{1}{2}\right)=55,35\)
\(x\cdot\frac{9}{2}=55,35\)
\(x=12,3\)

x*4+1/2*x=55,35
=x*(4+1/2)=55,35
=x*4,5=55,35
=55,35:4,5
=12,3

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
\(x\cdot4+\frac{1}{2}\cdot x=55,35\)
\(\Rightarrow x\cdot\left(4+\frac{1}{2}\right)=55,35\)
\(\Rightarrow x\cdot4\frac{1}{2}=55.35\)
\(\Rightarrow x\cdot4,5=55,35\)
\(x=55,35:4,5\)
\(x=12,3\)

\(\Leftrightarrow x\cdot\dfrac{9}{2}=55.35\)
hay x=12,3

x*4 + 1/2 * x = 55,35
x * ( 4 + 1/2 ) = 55,35
x * 4,5 = 55,35
x = 55,35 : 4,5
x = 12,3
Vậy x = 12,3
![](https://rs.olm.vn/images/avt/0.png?1311)
\(x\times4+\frac{1}{2}\times x=55,35\)
\(x\times\left(4+\frac{1}{2}\right)=55,35\)
\(x\times4,5=55,35\)
\(x=55,35:4,5\)
\(x=12,3\)
x x 4 + 1/2 x x = 55,35
x x (4 + 1/2) = 55,35
x x 4,5 = 55,35
x = 55,35 : 4,5
x = 12,3
Chúc bạn học tốt.
