For this case we have that by definition, the Greatest Common Factor or GFC of two or more numbers, is the largest number that divides them without leaving residue.
So:
We look for the factors of 18 and 36:
18: 1,2,3,6,9,18
36: 1, 2,3,4, 6,9,18 ...
Thus, the GFC of both numbers is 18.
Then, the GFC of
and 
is:

Answer:
Explain how subtracting 4/5 - 3/5 involves subtracting 4 and 3
Step-by-step explanation:
Trains A and B, 200 km apart on the same straight track, travel at speeds of 50 km/hr and 65 km/hr respectively. At the end of 1 hour, the distance between the trains could not be
A. 85 km
B. 115 km
C. 185 km
D. 215 km
Apparently, the answer is B.) 115 km, but I need a solution.
Answer:
C. He create a graph to show what he wants to charge.
Step-by-step explanation:
Answer: x > 3
Step-by-step explanation:
In order to find x, we must isolate it first.
Add one to both sides. It's now 4x < 12.
Now we divide both sides by 4, remember that every time we divide or multiply we must flip the inequality symbol.
The final answer is x > 3
Answer: 9b - 8b
Step-by-step explanation:
ou need two factors that you will multiply together to give you -72b^2 and at the same time when you add this two factors it will give you + b . Check; 9b X -8b = -72b^2 and 9b + (-8b) = b , that is why 9b and -8b are the factors and they will replace the middle value
