We should solve this using the order of operations, meaning we should start by distributing the 8 in the parentheses.
15k+8(11-k)
15k+88-8k
Now, we should combine our like-terms,
7k+88
There is nothing else we can do to this equation, so it is simplified. Using the math above, we can see the simplest form of this equation is 7k+88.
Answer: 1- 36 and 45 LCM is 180
2- 42 and 105 LCM is 210

Answer:
50%
Step-by-step explanation:
Let :
Winter = W
Summer = S
P(W) = 0.85
P(S) = 0.65
Recall:
P(W u S) = p(W) + p(S) - p(W n S)
Since, none of them did not like both seasons, P(W u S) = 1
Hence,
1 = 0.85 + 0.65 - p(both)
p(both) = 0.85 + 0.65 - 1
p(both) = 1.50 - 1
p(both) = 0.5
Hence percentage who like both = 0.5 * 100% = 50%
