Number 20:
A is at -2.5. The inverse is the opposite so 2.5
The difference is the result of a subtraction problem.
We are given two values that are being subtracted: 54 and a number, represented by 
So, represent this mathematically with 
.
Answer:
34347
Step-by-step explanation:
Use the formula s=p(1+r/k)^kt
