Answer:
7 to 3 is this answer
Step-by-step explanation:
if you noticed, with all the other ones they all have 3 : 7 in it. So by the process of elimination it's 7 to 3 that is different. I'll tell you why,
3 : 7, that is the ratio we have as an example. That's why it isn't the different one.
3 to 7, you say 3 : 7 as 3 to 7 to it still has the same ratio
3/7, this is how to type the fraction version of the ratio so it makes sense that it is the same one as 3 : 7.
7 to 3, if you haven't noticed yet, all of them has 3 : 7 as a counterpart. They are all the same but this one, this is 7 : 3 or 7 to 3. So with logic, this is the different ratio.
The answer is 1 and 5/7 as a proper fraction.
The answer is -48 when you substitute the -4
The answer is in the image below.

Answer:
Denote the distance from initial position of Emily to the park is D
=> As the first speed is 5 (mile/hour) and second speed is 9 (mile/hour) and total time is 1 and 5/9 hour, we have:
D/5 + D/9 = 14/5
=> (9D + 5D)/45 = 14/5
=> 14D/45 = 126/45
=> 14D = 126
=> D = 9 (mile)
Hope this helps!
