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.

Kelli and her family went to the beach for a vacation. They drove 293 miles in 7 hours to get there. ABOUT how many miles did they drive each hour?

This Question is calculated as:

7 hours = 293 miles

1 hour = x miles

Cross Multiply

7 hours × x = 1 × 293 miles

x = 293 miles/7 hours

x = 41.857142857 miles per hour

x ≈ 41.86 miles per hour

Hence, they drove 41.86 miles each hour

Solve the equation: <br> 2x + B= C<br><br> X=
Angelina_Jolie [31]
Add (-2X) to both sides:
2X + B + (-2X) = C + (-2X)
If we (rearrange) it into B + 2X + (-2X) = C + (-2X)
B + 2X - 2X = C + (-2X)
Since +2X - 2X = 0
B + 0 = C + (-2X)
B = C + (-2X)
B = C - 2X
