Answer:
A. C=125+5n
B. 30 Months
Step-by-step explanation:
275-125=150÷5=30
The function of the graph is -2
The ratio being 1:5:3, you would have to just make those numbers still in that ratio, but they have to add up to 180 degrees.The angles would be 20 degrees, 100 degrees, and 60 degrees. Hope that helped. :)
