Answer:
12
Step-by-step explanation:
Let the two points be represented by (x1,y1) and (x2,y2).
Distance between the two points is given by the formula:
![\[\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B%28x2-x1%29%5E%7B2%7D%2B%28y2-y1%29%5E%7B2%7D%7D%5C%5D)
----------------- (1)
In this case x1=-2,y1=6,x2=-2,y2=18.
Substituting the relevant values in the formula (1),
distance = ![\[\sqrt{(-2-(-2))^{2}+(18-6)^{2}}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B%28-2-%28-2%29%29%5E%7B2%7D%2B%2818-6%29%5E%7B2%7D%7D%5C%5D)
= ![\[\sqrt{0^{2}+12^{2}}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B0%5E%7B2%7D%2B12%5E%7B2%7D%7D%5C%5D)

Answer:
1. he eats 5 per day (5 less every day)
2. he starts with 83 pieces of candy
3. 53
4. on day 11
Step-by-step explanation:
1. self explanatory
2. self explanatory
3. 6*-5=-30 -30+83=53
4. put y as 28
28=-5x + 83 now solve for x
subtract 83 both sides
-55=-5x
divide -5 from both sides
11=x
In order to find out the answer , you just need to count :
Let's say that mary's collection is symbolized by x
2/3 x = 4h
x = 3/2 . 4h
x = 6h
The storybooks they have in total would be : 6h + 4h = 10 h
hope this helps
9 as a fraction of 15 is the same as saying what is 9 of 15 or 9 divided by 15. so your answer would be 9/15. Simply put it in fraction form. I hope this helped you!!
