Answer:
Mathematics can be completed through the use of logical thinking and the use of equations to figure out various problems.
Answer:
13. c
14.a
15.c
16.d
17.b
18.d
19.a
20.b
Step-by-step explanation:
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
