[tex]6 = \frac{2d}{5} \\ 6 \times 5 = 2d \\ 30 = 2d \\ \frac{30}{2} = d \\ \boxed{15 = d}[/tex]
[tex] = > 6 = \frac{2d}{5} [/tex]
[tex] = > 5 \times 6 = 5 \frac{2d}{5} [/tex]
[tex] = > 5 \times 6 = 2d[/tex]
[tex] = > 30 = 2d[/tex]
[tex] = > \frac{30}{2} = \frac{2d}{2} [/tex]
[tex] = > 15 = \frac{2d}{2} [/tex]
[tex] = > 15 = d[/tex]
[tex] = = > d = 15[/tex]
