\(\Rightarrow y\)x \(\left(4+0,5\right)\)\(=55,35\)

\(\Rightarrow\)\(y\)x \(4,5=55,35\)

\(\Rightarrow y=55,35:4,5\)

\(\Rightarrow y=12,3\)

chúc em hok tốt

Tìm y:

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

yx(4+0,5)=55,35

yx4,5=55,35

y=55,35:4,5

y=12,3

>>>>>Ai không hiểu chỗ nào trong đáp án của mình thì hỏi mình nhé!

y*(4+0,5)=55,35

y*4,5      =55,35

y            =55,35:4,5

y            =12,5

`!`

`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`

\(\Leftrightarrow x\cdot\dfrac{9}{2}=55.35\)

hay x=12,3

12,3

nếu X*4+1:2*X=55,35

thì 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

Lời giải

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

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

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

      \(x=55,35:\frac{9}{2}\)

      \(x=12,3\)

\(x\times4+\frac{1}{2}\times x=55,35\)

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

\(x\times4,5=55,35\)

\(x=55,35:4,5\)

\(x=12,3\)

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.

😁😁😁

\(x\times4+\frac{1}{2}\times x=55,35\)

\(x\times4+0,5\times x=55,35\)

\(x\times\left(4+0,5\right)=55,35\)

\(x\times4,5=55,35\)

\(x=55,35\div4,5\)​

\(x=12,3\)

Vậy ​\(x=12,3\)​
 

Ta có : x*4+x*1/2=55,35

              x(4+1/2) = 55,35

              x* 9/2     = 55,35

                     x =  12,3

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

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

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

\(\Leftrightarrow x=12,3\)

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

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

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

\(\Rightarrow x=55,35:4,5\)

\(\Rightarrow x=12,3\)

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

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

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

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

\(\Leftrightarrow x=\frac{123}{10}=12,3\)

(Tíck cho mìk vs nha!)

\(x\times4+\frac{1}{2}\times x=55,35\)

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

\(x\times\left(\frac{8}{2}+\frac{1}{2}\right)=55,35\)

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

\(x\times4,5=55,35\)

\(x=55,35\div4,5\)

\(x=12,3\)
