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:

$0.004(3y-60.5)=1$

$0.004(3y)-0.004(60.5)=1$

$0.012y - 0.242 = 1$

$0.012y = 1+0.242$

$0.012y = 1.242$

$y = \frac{1.242}{0.012}$

$y = 103.5$

$SOLUCION: y = 103.5$

$\frac{(0.5x-6)}{0.3} =\frac{0.1x}{0.3}$

$Simplicamos -los -denominadores.$

$0.5x-6 = 0.1x$

$0.5x-0.1x = 6$

$0.4x = 6$

$x = \frac{6}{0.4}$

$x = 15$

$SOLUCION: x = 15$

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

$\frac{(7.52x-1)}{2} = (3.46x+1)$

$7.52x-1 = 2(3.46x+1)$

$7.52x-1 = 6.92x+2$

$7.52x-6.92x=2+1$

$0.6x = 3$

$x = \frac{3}{0.6}$

$x = 5$

$SOLUCION: x = 5$
