Answer:
The 20th day
Step-by-step explanation:
On the first day, number of people who know the secret=2
Number of people On the second day =2X2=4
Number of people On the third day =4X2=8
We can see that on each passing day, the number keeps doubling.
This is an example of a geometric progression.
Now we are to determine the number of days when the number of people who know the secret will grow past 1,000,000
For the G.P. 2,4,8,...
a=2, common ratio, r= 2
Uₙ=arⁿ⁻¹
arⁿ⁻¹>1000000
2X2ⁿ⁻¹>1000000
2ⁿ⁻¹⁺¹>1000000
2ⁿ>1000000<2²⁰=1048576
2ⁿ<2²⁰
n<20
It means on the 20th day, more than 1 million people will have been told the secret
<span>2x - 12 = 14
Add 12 to both sides of the = sign to get rid of the "-12".
</span><span>2x - 12 <span>+ 12 </span>= 14 <span>+ 12</span>
2x = 26
Now divide both sides by 2 to isolate the x
</span><span>
2x / 2 = 26 / 2
x = 13.
The solution is x = 13.
Hope this helps!
Let me know if there's anything you're still confused about and I'll try to help you out.
Solving for x like this is definitely something you want to master and be able to do on your own, because you'll be doing it in future math.

Step-by-step explanation:
If the other two friend also bought tickets for x dollars as the first three, than: 3x+3•8+2x=5x+24
If other two friends bought tickets for y dollars,different amount than x, than: 3x+3•8+2y=3x+24+2y=3x+2y+24
