Answer:
um
Step-by-step explanation:
Anything to the zeroth power is equal to 1. (The numerator is equal to one because of this rule)
So.

The example of real life situations is: The cost of 30 green apples is €60
Rox wants to buy only 5 apples, how much will they cost her?
Cost of 30 green apples is €60.
Cost of 1 green apple = €60/30 = €2
(Using the concept of division of rational numbers)
Now, cost for 5 green apples =5 * €2 = €10
5+x=-9
Use the subtractive property of equality to isolate x.
5+x=-9
-5 -5
x=-14
The value that satisfies x is -14. You can check your work by substituting x as -14 and checking if the equation is satisfied.
5+x=-9
x=-14
5+(-14)=-9
5-14=-9
-9=-9
the answer is correct. Succinctly, x=-14.
