Answer:
The annual interest rate is 6.25%
Step-by-step explanation:
We have been given that
P = $50,000
I = $9,375
t = 3 years
r = ?
The formula for simple interest is given by

Therefore, the annual interest rate is 6.25%
2.73972603 or ... you can round to the nearest tenth... 2.7
(2, 8), (2, 5)
Just subtract the numbers that aren't the same.
8 - 5 = 3
So the distance is 3.
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:

Add 3x to both sides:

Add 6 to both sides:

Which is of course equivalent to

Divide both sides by 9

So, every number smaller than 2 is part of the solution of this inequality.
