All you need to do is divide -1/2 onto the other side.
-1/2x<-12
-12/ (-1/2)= 6 (a negative and a negative equals a positive)
Also, since you are dividing a negative, you flip the sign.
x>6
I hope this helps!

Answer: C
Step-by-step explanation:

It would be 625 because 5 to the fourth power is 5×5×5×5×5 which is equal to 3,125 and then it would be 3,125 over 5 which is 3,125÷5 which is equal to 625 so the answer would be 625
