Solve: the quantity 2x minus 20 divided by 3 = 2x
x = −5
x = −2
x = 2
x = 13

x = -5

Step-by-step explanation:

(2x-20) / 3 =2x

2x - 20 =6x

4x = -20

You start with 125 bacteria and they double every hour. You have six hours so the first hour 125 doubles to 250. Hour two 250 doubles to 500. Hour three 500 doubles to 1000. Hour four 1000 doubles to 2000. Hour five 2000 doubles to 4000. Hour six 4000 doubles to 8000. the answer is C
