Lnx+5lny-1/2lnz= ln(5x) - ln√z ==> ln[(5x)/√(z)]
Answer: C:800.B:1200.T:1600
Step-by-step explanation: If the ratio is proportional to the time spent on the marketing competition, then we can add the hours up: 4+6+8=18. Total amount divded by total hours -> 3600/18=200. So each hour worked is 200 dollars. Christine worked 4 hours, 4*200=800, Bianca worked 6 hours, 6*200=1,200, and Travis worked 8 hours, 8*200=1,600.
Answer:
A
Step-by-step explanation:
Given
12x + 7 < - 11 or 5x - 8 > 40
Solve each inequality
12x + 7 < - 11 ( subtract 7 from both sides )
12x < - 18 ( divide both sides by 12 )
x < - 
OR
5x - 8 > 40 ( add 8 to both sides )
5x > 48 ( divide both sides by 5 )
x > 
Solution is
x < -
or x >
→ A
