Answer:
140
Step-by-step explanation:
- 143,622 bacteria present on day 15
- the bacteria doubles twice a day
that means each day backwards, the bacteria is four times less the day before
therefore:
- on day 14, the number of bacteria is 143,622 / 4
which is 35,905.5
and so on!
so:
- day 13 = 8,976.375
- day 12 = 2,244.09375
- day 11 = 561.0234375
- day 10 = 140.255859375
this rounded to the nearest whole number is
= 140 bacteria
(you can't have a part of a bacteria!)
hope this helps! :)
-2 (3+5y-10) = 34
Step 1) -6-10y+20=34
Step 2) -10y+20=40
Step 3) -10y=20
Step 4) y = -2
Answer is -2
6 2/5 is the answer, because 15 1/2 divided by 2 2/5 is 6 2/5
