Answer:
14
Step-by-step explanation:
70% = 0.70
of means multiply or "×"
So, 0.70 × 20 = 14
6c-8-2c= -16
1st) reduce 6c - 2c = 4c, now te equation becomes:
4c - 8 = -16
2nd) add +8 to the left and right sides
4c - 8 + 8 = - 16 + 8
3rd) reduce the left and right sides:
4c + 0 = -8 → 4c = -8
4t) divide both sides by 4:
4c/4 = -8/4
and c = -2
