WebStep 1: Translate the word problem into inequalities. Let's start with establishing our variables. x=Jenn y=John. We know that Jenn and John want to drive at least 500 miles. At least generally means greater than or equal to. So if we incorporate the speed at which the two of them drive, we can say that: 50x+45y≥500. WebA system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. sharon welsh nurse practitionerWebFirst, let us clear out the "/3" by multiplying each part by 3.
