Explicación paso a paso:
x/16 = 4/8
x/16 = 1/2
x = (1*16)/2
x = 16/2
x = 8
9/20 = 36/x
9x = 20 * 36
9x = 720
x = 720/9
x = 80
5/x = x/80
xx = 5 * 80
x² = 400
x = ±√400
x = 20
x = -20
Respuesta:
1) x/16 = 4/8
Simplificamos 4/8 = 1/2
[tex]\frac{x}{16}=\frac{1}{2}[/tex]
[tex]\frac{16x}{16}=\frac{1\cdot \:16}{2}[/tex]
[tex]x=8[/tex]
2) 9/20 = 36/x
9x = 20 × 36
3) 5/x=x/80
5 × 80 = x.x
[tex]400=x^2[/tex]
[tex]x=20,\:x=-20[/tex]
