Answer:
1836 bacteria
Step-by-step explanation:
Now the data is a progression; 38,000, 33,820, 30,100 .........
We can find out what type of progression it is, in this case, we can see that it is a geometric progression because;
r= 33,820/38,000 = 30,100/33,820 = 0.89
So, for a geometric progression;
Un = ar^n-1
Where;
a = 38,000
r = 0.89
n = 27 days
Un = ???
Un = 38,000 * (0.89)^27 - 1
Un = 1836 bacteria
Answer:
3x-9=2x+4
-2x -2x
x - 9 = 4
+ 9 +9
<h2>
x = 13</h2>
First isolate the variable into one side.
Then simplify like terms.
Hope this helps.
