Answer:
Option B
Step-by-step explanation:
The slope of the line BC is,
![\frac{ - 2 - 8}{7 - 3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%202%20-%208%7D%7B7%20-%203%7D%20)
![= \frac{ - 10}{4} = - \frac{5}{2}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B%20-%2010%7D%7B4%7D%20%20%3D%20%20%20-%20%5Cfrac%7B5%7D%7B2%7D%20)
Since AD is altitude to BC, we can say AD is perpendicular to BC, so the slope of the line AD which is perpendicular line to BC will be,
![\frac{2}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B5%7D%20)

Answer:
Sydney is 45
Step-by-step explanation:
Let s represent Sydney's age. Then Devaughn's age is (s-14). The total of their ages is ...
s +(s -14) = 76
2s = 90 . . . . . . simplify, add 14
s = 45 . . . . . . . divide by 2
Sydney's age is 45.
___
<em>Check</em>
Devaughn's age is 45 -14 = 31. Their age total is 45 +31 = 76, as required.
Answer:
60
Step-by-step explanation:
3168 rounds to 3000
47 rounds to 50
So the estimate is 3000/50 = 60
Note: you are not looking for an exact answer. You are looking for a number that you can do in you head that tells you if you are doing it correctly.
The exact answer is 67.4 which is close to the estimated answer., but 60 is the answer you should feed in.
