Answer:
(x -t -250)/2
Step-by-step explanation:
The amount left from x after paying t and 250 is ...
x -t -250
If this is split into two equal parts, each share is ...
share = (x -t -250)/2
Answer:
(x + 15) / 2
Step-by-step explanation:
Distance = rate × time
d = (x² – 225) / (2x − 30)
d = (x – 15) (x + 15) / (2 (x – 15))
d = (x + 15) / 2
