The annual rate of depriciation would be approximately $1,166.60 per year.
Converting to base 10 can be done easily by writing a sort of digit expansion. In base 6, this number literally means

Simplifying this gives the value in base 10.

The answer is
.
Let's solve your equation step-by-step.
2b+3b=3
Step 1: Simplify both sides of the equation.
2b+3b=3
(2b+3b)=3(Combine Like Terms)
5b=3
5b=3
Step 2: Divide both sides by 5.
5b/5=3/5
So, the answer is
.
