Question

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

Giải giúp mik với

Answer 1

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

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

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

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

\(x=12,3\)

Answer 2

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

Answer 3

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

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

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

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

\(x=55,35\div4,5\)​

\(x=12,3\)

Vậy ​\(x=12,3\)​
 

Answer 4

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 : )))))
