Answer:
9 hours
Step-by-step explanation:
1 chapter ≈ .5 hour
18 x .5 = 9
1/3 + 2/9 equals 3/9
3/9 is then simplified to 1/3 :)
1. Write as an algebraic equation:
12 + n ≤ 2n - 8
2. Solve for n.
12 + n - 12 ≤ 2n - 8 - 12
n ≤ 2n - 20
n - 2n ≤ 2n - 20 - 2n
-n ≤ -20
Multiply both sides by -1 (this means you must flip the inequality sign).
n ≥ 20
FINAL ANSWER: n ≥ 20
Hope this helps! Feel free to ask for clarification.
The answer is 37!
(-8)^2 - 5(-8) + 7 = 111
(111)(1/3) = 37
