Answer:
16
Step-by-step explanation:
There are several ways to go at this. Perhaps the simplest is to put the expression into your calculator.
__
Using the rules of exponents, you recognize ...
a^-b = 1/a^b
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
__
So, we can rewrite the expression to be ...

This is showing a corresponding pair of angles. So x would equal 34 degrees. (If it was a linear pair, it would be 180-34)
Answer:
You can say there is no solution for a system of linear equation when the graphs are PARALLEL to each other.
ONE solution: when both lines intersect at one point
INFINITE solution: when the line goes on forever
NO solution: is when the lines are parallel to each other.
4a+7b-12c-8a-9b+12d
Now you have to combine like terms, so a and a, B and B etc.
4a-8a=-4a
7b-9b=-2b
No more like term
-4a-2b-12c+12d
Have a nice day
18 - 5.7 = 12.3
12.3 - 8.8 = 3.5
3.5 to a fraction = 3 1/2
So the answer = 3 1/2
