31.88 is the price 212.50*15% equals 31.88
Answer:
3 1/2
Step-by-step explanation:
You can do 1 1/3 + 3/4 + 2/3 + 3/4 which equals 3 6/12.
Now in fraction problems, they always want it in the simplest form, so the simplest form of 3 6/12 is 3 1/2.
Your answer is 3 1/2.

Answer:
Step-by-step explanation:
The focus lies on the x axis and the directrix is a vertical line through x = 2. The parabola, by nature, wraps around the focus, or "forms" its shape about the focus. That means that this is a "sideways" parabola, a "y^2" type instead of an "x^2" type. The standard form for this type is
where h and k are the coordinates of the vertex and p is the distance from the vertex to either the focus or the directrix (that distance is the same; we only need to find one). That means that the vertex has to be equidistant from the focus and the directrix. If the focus is at x = -2 y = 0 and the directrix is at x = 2, midway between them is the origin (0, 0). So h = 0 and k = 0. p is the number of units from the vertex to the focus (or directrix). That means that p=2. We fill in our equation now with the info we have:
Simplify that a bit:
Solving for y^2:
Multiply everything if not that than add
No
2(6-3x) = 12-6x
2(3x)+x = 7x
