Answer: 
Step-by-step explanation:
Let A be the event of getting a factor of 15 when a fair spinner numbered 1 - 5 spins and B be the event that a fair coin is tossed.
The factors of 15 = 
Then ,the probability of obtaining a factor of 15 is given by :-

The probability of getting a tail :-

Since both the events are independent , thus
The probability of obtaining a factor of 15 and a tail is given by :-

Hence, the required probability : 
1. 12 is your answer
2. -33 is your answer
12.8 / 8 = 1.6
8 / 5 = 1.6
SF = 1.6
so x = 6 * 1.6 = 9.6
answer
x = 9.6
Answer:
x= 12
Step-by-step explanation:
Multiply everything by 12 (making it easier to solve) to get
6x + 4x = 3x + 84
Simplify to get
7x = 84
Solve for x and get x=12
Answer:
Option B and Option D are the two answers
