Answer:
Segment
Step-by-step explanation:
It is a segment because it has two endpoints (the Earth and Moon). If it was a ray, it would go on forever in one direction. It doesn't, so the imaginary line is a segment.  
The first image is a segment, the second is a ray. 
Hope this helps. :)
 
        
             
        
        
        
If you have several different sized pizzas, you can compare their areas. So the area of a pizza is the length of the crust (circumference) divided by two times the distance from the edge to the middle (radius). Mathematicians use a special number called pi to calculate the circumference of a circle.

Cross multiply
3(2x + 1) = 5(2x - 5)
expand by using distributive property
6x + 3 = 10x - 25
-4x = - 28
   x = 7
