When boating at night, what does a single white light on a boat tell you?

When someone is navigating a boat at night and they see a white light on a boat. That means that you just encountered another vessel.

Explanation:

Hi, this is a very dangerous situation so please remember well that anytime you see a white light when you are navigating a ship at night it means there is another vessel in that direction. So, you have to provide it some space, because it will be difficult for both of the navigators to calculate the size of the other vessel. So, you have to make your course wider. In those cases also you can provide the other vessel a sound signal that you are incoming in the opposite direction.

x=3

step-by-step explanation:

this is really simple i saw that there was only one term (5x) and thought if that was 15 what would i have to multiply everything else to get it there? well if 5x became 15 then x would have to be 3 so plug the 3 in the x for the other equations and you get 15 for the other ones. so there you go. : )
