The temperature dropped 66 degrees
Step-by-step explanation:
Answer:2 hours 15 mins = 2 1/4 hours
2 1/4 hours = 25 miles
1 hour = 25 ÷ 2 1/4 = 25 ÷ 9/4 = 25 x 4/9 = 11.1 miles
Answer: 11.1 mph

Answer:
D
Step-by-step explanation:
It’s correct
When you subtract the length of the base from the length of the side, you get
(ax+9) - (4x+b) = (a-4)x +(9-b)
Well, think of the dragonfly's speed as a ratio of miles/hours, thus making it 36/1 (as a fraction). Now to solve this, set the known ratio equal to the ratio you want to find and solve for the missing variable (x) which is hours. Cross multiply to find your (x) hours.
