1. The ratio of diamonds to stars was 3 to 11, and three times the number of diamonds was 2 less than the number of stars. How many were diamonds?

​

Respuesta :

Answer:

There were 3 diamonds.

Step-by-step explanation:

[tex]\frac{Diamonds(D)}{Stars(S)}=\frac{3}{11}[/tex]

Therefore, [tex]11D=3S[/tex]

[tex]S=3D+2[/tex]

Therefore,

[tex]\frac{11D}{3}=3D+2[/tex]

[tex]11D=9D+6[/tex]

[tex]2D=6[/tex]

[tex]D=3[/tex]
