Answer:
- x = 37
- DG = 22
- AG = 44
- AD = 66
Step-by-step explanation:
We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...
(x+7) = 2(x -15)
x + 7 = 2x - 30 . . . . eliminate parentheses
37 = x . . . . . . . . . . .add 30-x
Then AG = 37+7 = 44
and DG = 37-15 = 22.
Of course, AD = AG +GD = 44 +22 = 66
Let's say x is J because it's Lemon Juice.
It's said that the pH of J is less than 4 so: pH(J) < 4 and pH(J) is greater than 1.5 so: pH(J) > 1.5
Now we can construct:
![1.5 < pH(J) \wedge pH(J) < 4](https://tex.z-dn.net/?f=1.5%20%3C%20pH%28J%29%20%5Cwedge%20pH%28J%29%20%3C%204)
Or simply:
![1.5 < pH(J) < 4](https://tex.z-dn.net/?f=1.5%20%3C%20pH%28J%29%20%3C%204)
We can also write this with an interval:
![pH(J)\in(1.5, 4)](https://tex.z-dn.net/?f=pH%28J%29%5Cin%281.5%2C%204%29)
Hope this helps.
