60 = 5(r)
60 means total amount of mint
5 means minutes per ride
R is the amount of rides
R = 30 or 30 rides
Answer: The coordinates of the circumcenter is
.
Explanation:
The coordinates of triangle DEF are D(1,3) E (8,3) and F(1,-5).
Distance formula,




Since triangle follows pythagoras theorem,

Therefore the given triangle is a right angle triangle.
Or plot these points on a coordinate plane. From the figure we can say that the triangle DEF is a right angle triangle.
The circumcenter of a right angle triangle is the midpoint of the hypotenuse.
The hypotenuse is EF. The midpoint of EF is,

Therefore, the coordinates of the circumcenter is
.
So 9x<18 can be factored out into
9(x)<9(2)
you can divide both sides by 9
x<2
so the solution is any number more than 2, but not 2
Step-by-step explanation:
A and B works because both are 8x+4y
