Answer:
ok so for a ≤ 20 it is A is less than or equal to 20
a ≥ 25 is A is greater than or equal to 25
Explanation:
whenever you have a symbol like ≥, where it has a line under it, it means it could be equal to. And when the symbol is like a<20 (where < is the alligator it eats the bigger number so 20 is larger) And this means a is less than but since there is ≥ then its Equal to as well. :) sorry if this is confusing i will be willing to further explain if needed.
