Answer:
- Possible (19, 21, 36)
- Not Possible (2, 7, 17)
Explanation:
a - 7 > 10
~Add 7 to both sides
a > 17
With this being said, any value greater than 17 will be a solution. In the choices given, only 19, 21, and 36 are greater so those are the possible solutions. The others are not solutions.
Best of Luck!
