Answer:
x > -6
Step-by-step explanation:
Considering the least common factor of 15 and 18, it is found that they will depart from the central station at the same time at 11 AM.
<h3>How to find the time it takes for periodic events to repeat at the same time?</h3>
To find the time that passes between the events happening at the same time, we need to find the least common multiple of the periods.
In this problem, the periods are of 15 and 18, hence their lcm is found as follows:
15 - 18|2
15 - 9|3
5 - 3|3
5 - 1|5
1 - 1
Hence:
lcm(15,18) = 2 x 3 x 3 x 5 = 90 minutes.
They will depart from the central station at the same time in 90 minutes from 9:30 AM, hence at 11 AM.

Answer:
Definition: Exponents, or powers, are a way of indicating that a quantity is to be multiplied by itself some number of times.
Example: 
Answer:
D
Step-by-step explanation:
D is the correct answer
Answer:
See explanation below.
Step-by-step explanation:
Take the original number and move the decimal from right to left, one place at a time. Stop just next to the last number, and count the number of times you moved the decimal. The number of times it moved is the exponent of 10. See examples below:
285 is the same as 2.85 x 10^2
3721 is the same as 3.7 x 10^3
88700000 is the same as: 8.87 x 10^7
Hope this helps!! Have an Awesome Day!! :-)
