Answer:
36
Step-by-step explanation:
We need to find the LCM of the two numbers because we need to know the lowest number that 12 and 9 are both in.
12 × 1 = 12
12 × 2 = 24
12 × 3 = 36
12 × 4 = 48
9 × 1 = 9
9 × 2 = 18
9 × 3 = 27
9 × 4 = 36
We can see that 36 is the lowest number that occurs both in 12 and 9 so the blue and red light will both link at 36 seconds
% Decrease = Decrease ÷ Original Number × 100
Divde 11,625 by 12,500 and multiply the answer by 100.
11,625 ÷ 12,500 × 100 = 93
The percentage reduction is 93%.

</span><span>2x(x) - 2x(5) + 3(x) - 3(5) (applying distributive property)
</span><span>2x^2 - 10x + 3x - 15 (simplifying)
</span><span>2x^2 - 7x - 15 (combining like terms)
I found this as an example from research. I do hope this helps. I have trouble in the same subject or I used to anyway. I hope this is what you were looking for. :)</span></span>
