16/25 people bought at least 1 book.
I believe it is 6 hope it helps
1/2 x^2 - x + 5 = 0
Multiply through by 2 to get:
x^2 - 2x + 10 = 0
; where a = 1, b = -2 and c = 10
Therefore, x = 1 + 3i or x = 1 - 3i
Answer:
The answer to this is -19.
This is the answer because After you distribute, You should have:
22-2k=-4k-16
Then you Add 2k to both sides. then you get this:
22=-2k-16
Then you Add 16 to both sides. Then you get this:
38=-2k
Then you divide both sides by -2. And you get:
-19
