-6(2+a) = -48
Distributive property
-12 -6a = -48
Add 12 to both sides
-6a = -36
Divide both sides by -6 and you get a= 6

Answer:
$295.01
Step-by-step explanation:
Using the compounding continuously formula, we are looking for A. We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4. Filling in we have:
![A=190e^{(.11)(4)}](https://tex.z-dn.net/?f=A%3D190e%5E%7B%28.11%29%284%29%7D)
Simplifying that multiplication:
.
On your calculator, raise e to the .44 power to get
A = 190(1.552707219) and
A = $295.01
500/6.7=74.6268.....
500 miles/6.7 hours : 74.63 miles/1 hour
The average speed of the car was 74.63 miles/hour
