Conversational speech is 65 dB as a known fact.

Answer:
7 years
Step-by-step explanation:
Your equation <u>should</u> read = 200 * e^(.08 t) = 350
solving for t = 6.99 yrs ~~ 7 years
On the left side of the equation, we have 3x or 3 * x. But in algebra, we usually just do 3x.
We need to find a value for x that when multiplied by -3 equals to -216.
We can find the value for x by dividing both sides by the coefficient of 3x. Which is 3.
3x / 3 = -216 / 3
x = -72
So, x is equal to -72.
