Answer:
erm....
Step-by-step explanation:
you are gonna have to give us a little bit more of the background info here!
r/3 + t = w to get r by itself (Which I think is your question)
r/3 + t = w subtract t from both sides
r/3 = w - t and times by 3 on both sides
r = 3(w-t)
The answer is 20.24
After rounding, it becomes 20.2
Answer: $73.80 in interest over a 6 year period
Step-by-step explanation:
600*0.0205= 12.30*6=73.80
we know that
In a right triangle
Applying the Pythagorean Theorem

where
a and b are the legs of the triangle
c is the hypotenuse of the triangle
Step N 
<u>Assume that the third side is a leg</u>
In this case we have


Solve for b

substitute the values



Step N 
<u>Assume that the third side is the hypotenuse</u>
In this case we have


substitute the values



Step N 
<u>Find the difference of the third sides</u>

therefore
<u>the answer is</u>
