Answer:
12/52= 6/26= 3/13 of the people are men
Factoring the expression would be 6a(2a^2+4a-1)
So the probability of rolling a number greater than 2 is 4/6. So 4/6 times 150 should give you the answer 100.
The answer is 40, take 21 from the last equation solved and add 8 to it then add 11
It would be $40.50 because the pens are 27 pounds and the first 20 office supplies are $12, the next 30 are $10, and the remaining 37 would be $18.50
