D. X=130 but im not sure if this is correct
Answer :
- Total number of people in the room = 18
- Number of people with red hair = 2
- Number of people not with red hair = 18 - 2 = 16
- Probability of picking a person who doesn't have red hair =

Probability = 16/18
Reduce the fraction with 2
Probability = 8/9
Just do 6 x 0.2 to reverse the division
So the answer is 1.2
I think
14) You would put 14 over unknown is poportional to 40 over 100. Then multiply 14 by 100 then divide it by 40 to receive 35.
23.) x=2
24.)same
25.)x=3
26.)x=2
27.)x=3
28.)x= -35/11
