Answer:
If rounded to the nearest 10 bacteria, then it would be 500 bacteria.
Step-by-step explanation:
First multiply 150 by two in order to get 300, that leaves 4 hours to figure out. From there you can figure out the rest by seeing that 4 is 2/3 of 6. I converted it into the decimal number .66. Multiply 300 by .66 to get 198 and then add it to 300 to get 498. Then just round it up to the nearest 10 bacteria which leaves you with the final answer of 500 bacteria.
(-4)^-3 = 
-4^-3 = 
Basically in this situation there is no difference whether parenthesis are used or not.
So you have 3 and you want to get rid of 2 2/5. 3-2 is 1 1-2/5 is equal to three fifths, which is the answer.
So first he has to divide both sides by 8
wat
he multiplied the right side by 8 but divided left by 8
that is wrong
answer is 4th option

13x u add parentheses since two negatives positive
