Abiologist is recording the loss of fish in a pond. he notes the number of fish, f, in the pond on june 1. on july 1 there were 63 fish in the pond, which is 52 fewer fish than were in the pond on june 1. which equation represents this situation? a. f – 52 = 63 b. f – 63 = 52 c. 63 – f = 52 d. f – 63 = –52

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

What is the location of point g, which partitions the directed line segment from d to f into a 5: 4 ratio? –1 0 2 3
