First bring 3x to the other side, which will give you -2y= -16-3y. Then divide everything by -2, which will give you y=8+3/2x
It would take about 5 hours for them two to work together, because if you add 2+3 you will get 5 and they are asking in total.

Answer:
The probability of exercise in cruise ships = 73
Step-by-step explanation:
Let A be the probability of rock climbing
Let B be the probability of ice skating
Let C be the probability of fitness center
P(A) = 36, P(B) = 44, P(C) = 27
P(A ∩ B) = 14, P(A ∩ C) = 11, P(B ∩ C) = 9
P(A ∩ B ∩ C)=0
By formula,
P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B) − P(A ∩ C) − P(B ∩ C) + P(A ∩ B ∩ C).
Substituting the values in the above formula,
P(A ∪ B ∪ C) = 36 + 44 + 27 - 14 - 11 - 9 + 0
= 107 - 14 - 11 - 9
P(A ∪ B ∪ C) = 73
Answer:
120
Step-by-step explanation:
The formula for permutations is n!/(n-r)!.
6=n and 3=r, and if you plug those numbers in you would get 120
