Aculture started with 2,000 bacteria. after 7 hours, it grew to 2,600 bacteria. predict how many bacteria will be present after 15 hours. round your answer to the nearest whole number

Look at explanation for answer...

Step-by-step explanation:

This could be turned into a simple proportion if you want to do it that way :)

1.) First, use the proportion bacteria over time.

2.) It should set up to look like this:  2,600        X

                                                            =

                                                               7             15

3.) You then do your math (2,600 * 15) (39,000 / 7)

Your answer then comes out to be: (rounded) 5,571 bacteria

the answer is 3,512.  I just took the test and got the answer below me wrong.  So, this should be what you are looking for.

Step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
