This is true, not having a navy has shown itself to be a weakness of many nations/civilizations in the past. And there are also good reasons why this is so. Not having a navy strongly impacts a civilizations ability to maneuver around certain points and go around them. It also limits the ability to trade with other natons. Not to mention the additional value of having the firepower of ships (those that had cannons later on at least).
A Linear inequality with a variable is the type of inequality, where they are real numbers. If, the linear linear is also called first degree inequality.
In general, to solve any system of inequalities, we trace, in the same coordinate system, the region that represents the solution of each of the inequalities that make up the system. The system solution will then be given by the intersection of these regions. The following two scenes show examples of systems of inequalities involving linear and quadratic inequalities.
I'll need a little bit more information than that, however the answer that best suits the question is: White male settlers. They were payed to settle the west.<span />
