First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.
Answer: 2
Step-by-step explanation: subtract by 2 every time.
Answer: x = 995
Step-by-step explanation:
In this equation our log doesn't have a base so it is given the default base of 10. This makes our equation really.

Now we put every equation as the exponent of our base 10 looks like this:

Now we cancel out the log base 10 and the 10. We are left with:
(x+3) + (2) = 10^3
Lastly solve for x
x + 5 = 1000
x = 995
Two events are mutually exclusive if they cannot occur at the same time.
The only number greater than 5 is 6, which is an even number so the answer would be D.
