Answer:
x = 47
Step-by-step explanation:
KY + YV = KV
KY + 22 = x
KY = x - 22
By angle bisector property:
![\frac{TK}{TV} = \frac{KY}{YV} \\ \\\frac{87.5}{77} = \frac{x - 22}{22} \\ \\ x - 22 = \frac{87.5 \times 22}{77} \\ \\ x - 22 = \frac{1,925}{77} \\ \\ x - 22 = 25 \\ \\ x = 25 + 22 \\ \\ x = 47](https://tex.z-dn.net/?f=%20%20%5Cfrac%7BTK%7D%7BTV%7D%20%20%3D%20%20%5Cfrac%7BKY%7D%7BYV%7D%20%20%5C%5C%20%20%5C%5C%5Cfrac%7B87.5%7D%7B77%7D%20%20%3D%20%20%5Cfrac%7Bx%20-%2022%7D%7B22%7D%20%20%5C%5C%20%20%5C%5C%20x%20-%2022%20%3D%20%20%5Cfrac%7B87.5%20%5Ctimes%2022%7D%7B77%7D%20%20%5C%5C%20%20%5C%5C%20x%20-%2022%20%3D%20%20%5Cfrac%7B1%2C925%7D%7B77%7D%20%20%5C%5C%20%20%5C%5C%20x%20-%2022%20%3D%2025%20%5C%5C%20%20%5C%5C%20x%20%3D%2025%20%2B%2022%20%5C%5C%20%20%5C%5C%20x%20%3D%2047)
The answer is 10 for Plato users, 15 plus 5 divided by 2 = 10
Is there a second line in choice d?
The total number of magazine copies that the bookstore has is 96.
On the first day, the bookstore sold 1/3 copies ofmagazine among the total of 96.
Then the number of magazines sold on the yesterday = 96 * (1/3)
= 32
Number of magazines left in the bookstore now = 96 - 32
= 64
So the bookstore sold 23 magazines on the yesterday.
Number of magazines sold by the bookstore today is 1/8 of the total magazines left.
Then the number of magazines sold today by the bookstore = 64 * (1/8)
= 8
Then the number of copies that the bookstore has left = 64 - 8
= 56
There are 2 bananas because 8 divided by 4 is 2. Hope this helps
