<span>Tali is running at 5 miles per hour.
In 12 minutes she runs 1 mile,
in 1 minute she runs 1/12 mile,
so in 60 minutes (one hour) she would run 60/12 = 5 mph
Sandra is running at 10 miles per hour, this is twice as fast as Tali (5 mph x 2 = 10 mph).
It takes Sandra 6 minutes to run a mile.
Sandra runs 10 miles in an hour, so to run one mile would take her one tenth of an hour or 6 minutes.</span>
Alright! First you'd have to subtract the flat fee of the mug which is $8.95, then you'd have to divide by the rate which is $1.50. Your equation would be:
(26.95 - 8.95) ÷ 1.50 = r
Then you solve using your head.. lol.
(26.95 - 8.95) = 18.
(18 ÷ 1.50) = 12.
R = 12.
Hope this helps :).
Answer:
C
Step-by-step explanation:
The first step would be to subtract 9 from both sides. We want to get x by itself on one side, so we subtract 9, and whatever we do to one side, we have to do to the other. Hope this helps.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the number line is not given. The general explanation is as follows;
First, record the time she hung up (say, time = x)
To rewind 15 minutes back means, x - 15
So, point on the number line will be x - 15
Take for instance
![x = 45](https://tex.z-dn.net/?f=x%20%3D%2045)
The point on the number line will be:
![x - 15 = 45 - 15](https://tex.z-dn.net/?f=x%20-%2015%20%3D%2045%20-%2015)
![x - 15 = 30](https://tex.z-dn.net/?f=x%20-%2015%20%3D%2030)
<em>See attachment for illustration</em>
Assuming the function is
![f(x)=\dfrac32\left(\dfrac52\right)^{x-1}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cdfrac32%5Cleft%28%5Cdfrac52%5Cright%29%5E%7Bx-1%7D)
, you can define an equivalent recursive function as
