Answer:
Z> 4
So Z> 2 is true
Step-by-step explanation:
Given that:
Z-2>2
Adding 2 on both sides
Z-2 + 2 >2 + 2
Z > 4
hence the equation Z > 2 is true

Answer:

Step-by-step explanation:
Assuming the problem is asking you to factor out the formula, it can be done easily by finding a common number with the two givens.
4 goes into both 12 and 16 evenly, so we will use this to factor. But that's not all, we have the n-variable to worry about.
Look at the n-variable exponents in the problem, take the highest power that can go be subtracted from both and use that. We have a
and
. Since 5 can't go into 3, we must use 3 to factor.
Our factoring variable will therefore be
. Now, use this to simply divide and get the answer:

So how did we get this? For the whole numbers, we have to divide: (12/4, 16/4). Next, we have to minus the exponents since we are dividing.
When dividing the 12 and 4, minus the
and
to get
. Get rid of the
term for the 16 and leave the 4. And there's your answer!
A)4/13 would be the larger number since if you were to try to add them, 4/13 = 40/130 and 3/10 = 39/130, 40/130 > 39/130
B) A rational number between them would be 39.5/130.
