Answer:
800
Step-by-step explanation:
In order to get the new population of bacteria in <em>690 minutes</em>, you have to know how often the bacteria will divided in the time frame. So, you have to <em>divide </em><em>690 minutes </em><em>by </em><em>230 minutes.</em>
- 690 min. ÷ 230 min. = 3 times
The bacteria wil<u>l double its colony 3 times in 690 minutes</u>.
- <em>First division:</em> 100 x 2 = 200 bacteria
- <em>Second division:</em> 200 x 2 = 400 bacteria
- <em>Third division:</em> 400 x 2 = 800 bacteria
Therefore, the population of bacteria will be 800 in 690 minutes.

Here you go mate
Step 1
4n−m+3p+2m−n−p Equation
Step 2
4n−m+3p+2m−n−p Simplify by combining terms
(-m+2m)+(4n+-n)+(3p+-p)
Step 3
(-m+2m)+(4n+-n)+(3p+-p) Add them together
m+3n+2p
Answer
m+3n+2p
3x + 8 = 17
Subtract 8 from both sides
3x + 8 - 8 = 17 - 8
Simplifying
3x = 9
Divide both sides by 3
3x/3 = 9/3
Simplifying
x = 3
Answer
x = 3
Width = (7,6) - (7,3) = 3
height (7,3) - (2,3) = 5
