Answer:
36 mph
Step-by-step explanation:
First, we have to find the unit rate of the money.
Since it's 15 dollars for each mile over the speed limit, divide 15 by 165.
The answer is 11, which means he was going 11 mph over the speed limit.
Add 11 to 25, and you get 36
20 = 40e^-0.1446t
e^-0.1446t = 0.5
t = ln 0.5 / -0.1446
t = 4.8 days
Answer:
x = all real numbers.
Step-by-step explanation:
3 x minus 8 = negative x + 4 (x minus 2)
3x - 8 = -x + 4(x - 2)
3x - 8 = -x + 4x - 8
3x - 8 = 3x - 8
3x - 3x = -8 + 8
0 = 0
Since the result is a true statement, but 0 = 0, x is equivalent to all real numbers.
Hope this helps!
