hey everybody,

i'm new to the forums and i'm new to math too. so please excuse me if my questions seem pretty elementary. i was wondering if you could not only provide the answer but also explain "how" you came to the answer. thanks man......i appreciate it.

a 3 inch bolt passes through 1 1/2 inches of pine board, a 1/16 inch washer, and a 1/8 inch nut. how many inches does the bolt extend beyond the board, washer and nut if the head of the bolt is a 1/4 inch long?
