Answer:
9m+6m^2n
Step-by-step explanation:
12mn-3mn=9mn
4m^2n+2m^2n=6m^2n
==> 9m+6m^2n
or rewrite as 3m(3+2mn)
She would have to work at least 12 hours.
At Chili’s, she would be paid 11.75x + 33 per week, with x being the number of hours she worked.
At the Cheesecake Factory, Giselle would be paid 14.50x per week, with x being how many hours she worked.
We want to know how many hours Gisele would have to work for her pay at the Cheesecake Factory to be more than her pay at Chili’s
The inequality 11.75x + 33 < 14.50x is what has to be set up to solve the problem. At how many hours will the pay on the left be less than the pay on the right?
11.75x + 33 < 14.50x
33 < 2.75x
12 < x
So Giselle has to work greater 12 hours a week for her to make more money at the Cheesecake Factory.
117 - 30 = 87
87/3 = 29
The car was towed 29 miles

Answer: r = C/(2pi)
This is the same as writing 
=========================================================
Explanation:
pi is some number (approximately 3.14) which means 2pi is also some number (roughly 6.28)
Saying c = 2pi*r means we have 2pi times r, and the result is the circumference c. To isolate r, we'll undo the multiplication. We'll undo it by dividing both sides by 2pi like so
C = 2pi*r
C/(2pi) = r
r = C/(2pi)
in which we can write it like 
So whatever C is, we divide it over 2pi (aka roughly 6.28) to get the radius.
-----------------
Extra Info (Optional Section):
As an example, let's say the circumference of the circle is 628 feet. This means the distance around the circle is 628 feet. So C = 628 would lead to...
r = C/(2pi)
r = C/(6.28)
r = 628/(6.28)
r = 100
So the radius would be roughly 100 feet.
16 + 4x = 10 + 14
16 + 4x = 24.
4x = 24 - 16
4x = 8
x = 8 ÷ 4
x = 2
8x = 2 × 8
8x = 16
Final answer = 16.
