The manager turns on the restaurant's two neon signs at the same time. Both signs blink as they are turned on. One sign blinks every 9 seconds. In how many seconds will they blink together again? Explain how you got your answer. Need help please, thank you!

When does the other sign blink? After how many seconds?

two neon lights are turned on at the same time both signs blink as they are turned on. one sign blinks every 9 seconds the other sign blinks every 15 seconds in how many seconds will they blink together again /

To find out when the two signs will blink together again, we need to calculate the least common multiple (LCM) of their blinking intervals.

Let's start by finding the LCM of 9. To do this, we can list the multiples of 9 and find the first common multiple:

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, ...

Since we need to find the LCM with another number, let's consider the second sign's blinking interval as well. You didn't mention the interval for the second sign, so let's assume it blinks every n seconds.

Multiples of n: n, 2n, 3n, 4n, 5n, 6n, 7n, 8n, 9n, 10n, 11n, 12n, ...

Now, we need to find the first common multiple between 9 and n. Once we know this, we'll have our answer.

Looking at the multiples, we can see that the first common multiple of 9 and n is 9n. Therefore, the two signs will blink together every 9n seconds.

To find the value of n, we would need to know the blinking interval of the second sign. Once we have that information, we can substitute it into the equation 9n to get the final answer.

If you provide the blinking interval for the second sign, I can help you determine when they will blink together again.
