10 hours : 15 logs
x hours : 9 logs
15*x = 9*10 => x=9*10/15=6 hours
With n logs,
x=n*10/15=2n/3 hours where n is the number of logs.
The mode is the number that appears most often. The answer is A.3.
Answer:
4 < x < 6
Step-by-step explanation:
In this question, you would solve the inequality.
Solve:
3 < 2x - 5 < 7
Add 5 to both sides of the inequality.
8 < 2x < 12
Divide both sides of the inequality by 2.
4 < x < 6
Your answer would be 4 < x < 6

Hope you could get an idea from here.
