Answer:
Step-by-step explanation:
1) If 
is needed to cover 
than we need 3 more: ![\frac{5}{6}(3)=\frac{15}{6} =2\frac{3}{6} gallons2) But we still need to add the beginning [tex]\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%283%29%3D%5Cfrac%7B15%7D%7B6%7D%20%3D2%5Cfrac%7B3%7D%7B6%7D%20gallons%3C%2Fp%3E%3Cp%3E2%29%20But%20we%20still%20need%20to%20add%20the%20beginning%20%5Btex%5D%5Cfrac%7B5%7D%7B6%7D)
: 
8 over 20 equals 6 over 15
The first part of the set tells us that x is less than -5.
The second part tells us that x is greater than 5.
The intersection sign in the middle tells us to find "common" item in the first part and second part.
<u><em>Is there any number both greater than 5 and less than -5? No!</em></u>
So our solution doesn't exist and is the empty set.
ANSWER: The empty set
