Question

resuelva las siguientes ecuaciones a decímales
0.004(3y-60,5)=1

(0,5x-6)/0.3=0,1x/0.3

(7,52x-1)/2=(3,46x+1)

Answer 1

Respuesta:

Explicación paso a paso:

[tex]0.004(3y-60.5)=1[/tex]

[tex]0.004(3y)-0.004(60.5)=1[/tex]

[tex]0.012y - 0.242 = 1[/tex]

[tex]0.012y = 1+0.242[/tex]

[tex]0.012y = 1.242[/tex]

[tex]y = \frac{1.242}{0.012}[/tex]

[tex]y = 103.5[/tex]

[tex]SOLUCION: y = 103.5[/tex]

[tex]\frac{(0.5x-6)}{0.3} =\frac{0.1x}{0.3}[/tex]

[tex]Simplicamos -los -denominadores.[/tex]

[tex]0.5x-6 = 0.1x[/tex]

[tex]0.5x-0.1x = 6[/tex]

[tex]0.4x = 6[/tex]

[tex]x = \frac{6}{0.4}[/tex]

[tex]x = 15[/tex]

[tex]SOLUCION: x = 15[/tex]

-------------------------------------------------------------------------------------------------------

[tex]\frac{(7.52x-1)}{2} = (3.46x+1)[/tex]

[tex]7.52x-1 = 2(3.46x+1)[/tex]

[tex]7.52x-1 = 6.92x+2[/tex]

[tex]7.52x-6.92x=2+1[/tex]

[tex]0.6x = 3[/tex]

[tex]x = \frac{3}{0.6}[/tex]

[tex]x = 5[/tex]

[tex]SOLUCION: x = 5[/tex]
