Answer:
1 circle
Step-by-step explanation:
Given two circles (red circles on the diagram).
There are two tangent circles to both of the given circles (blue circles on the diagram), and only one of them is passing through the point (0,5).
Let's check it.
The equations of the tangent circles are
![x^2+y^2=9\ [\text{Smaller tangent circle}]\\ \\x^2+y^2=25\ [\text{Larger tangent circle}]](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D9%5C%20%5B%5Ctext%7BSmaller%20tangent%20circle%7D%5D%5C%5C%20%5C%5Cx%5E2%2By%5E2%3D25%5C%20%5B%5Ctext%7BLarger%20tangent%20circle%7D%5D)
Check whether point (0,5) lies on the smaller circle:

No
Check whether point (0,5) lies on the larger circle:

Yes
<u>Answer: </u>1 circle
Is the answer to your question 4/4?
Answer:
Part A. 4x
Part B. Mr. Jefferson could ride 3 miles in 12 minutes
Step-by-step explanation:
Part A. 4 being the time it takes him to travel 1 mile and x being the number of miles rode.
Part B. To find the time it took him to travel each mile I divided 20 by 5 which gave me four. Then to find the miles he could ride in 12 minutes I divided 12 from 4 which gave me three, stating that he could travel 3 miles in 12 minutes.
