(3640 - 3250) / 3250 = 390 / 3250 = 39 / 325 = 3 / 25 = 12%
(4100 - 3640) / 3640 = 460 / 3640 = 46 / 364 = 23 / 182 = 12.637...%
(n^-3)^6=n^-18=1/n^18
the answer is D
Answer:
100 hours
Step-by-step explanation:
Law firm A = 350x + 22,000,
Law firm B = 410x+16,000
Where,
x = number of hours of legal assistance
What number of hours of legal assistance makes the equation 350x+22,000 = 410x+16,000 true?
Equate the legal fees of the two law firms
350x + 22,000 = 410x + 16,000
Collect like terms
350x - 410x = 16,000 - 22,000
-60x = -6,000
Divide both sides by -60
x = -6,000 / -60
= 100
x = 100 hours
The number of hours of legal assistance makes the equation true is 100 hours
Yes, (-5,-6) is a solution to the equations!
