Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7
Answer:
Final answer is A. 
Step-by-step explanation:
From table we see that there are 7 places in the list.
Event A = The place is city.
Then
indicates the place is NOT city.

Answer:
(3V)/A = h
Step-by-step explanation:
V = 1/3 Ah

*3 *3
3V = Ah
/A /A
(3V)/A = h
