5. 25 = x + 3
It is a one step equation. You just need to subtract 3 on both sides to get x.
6. 2b - 7 = 15
This is a two step equation. You need to add 7 on both sides and then divide both sides by 2 to get b.
7. 10m = 90
Finally, this is a one step equation. You need to divide both sides by 10 to find m.
Answer:
The answer is 6
Step-by-step explanation:
For this case we have a function of the form:

Where,
A: it is the initial amount
b: is the growth rate
x: is the number of years
Substituting values we have:

We have a growing exponential function because the value of b is greater than 1.
