Answer: c = 8
Step-by-step explanation:
Simplifying
9c + -3c = 48
Combine like terms: 9c + -3c = 6c
6c = 48
Solving
6c = 48
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Divide each side by '6'.
c = 8
Simplifying
c = 8
Answer:

Step-by-step explanation:
The change of distance over time of the plain A is 300 mi/hour and 200 mi/hour for plane B. O is the point of the airport.
So, the distance from A to O AO = 90 miles and BO = 120 miles.
Now, we have a right triangle here. We can use the Pythagorean theorem, so the distance between the planes will be:
(1)


If we take the derivative of the equation (1) we could find the change of the distance between planes.


Finally,

I hope it helps you!
Answer:52,425
Step-by-step explanation: If you add all of the positive assets you end up with 15,050 but if you add 71,975 you get exactly 87,025 but when you add the liabilities you get -19,550 when you add those two numbers you get 52,425
Hope this helps!
Answer:
8x+4 and 10x+4
Step-by-step explanation:
Using the distributive property, you times 8 by x and then 8 by one half: 8x & 8*1/2. 8x+4
You then do the same for 10(x+2/5): 10x and then 10 divided by 5 and times by 2. This leaves you with 10x+4.
I hope this helped. :)
