______

Answer:

None of them is correct.

___________________

Arati posted a comment on her blog. Each day the number of responses to her comment was 125% of the number she received on the p
zvonat [6]

If the next number is 125% of the previous number, that means that the previous number is increasing by 25% each time.

The multiplier for increasing by 25% is:

(100 + 25) ÷ 100 = 1.25

So on day one, there are 64 responses. That means on day two, there will be:

---> 64 x 1.25 = 80 responses

On day 3, there will be:

---> 80 x 1.25 = 100 responses

Finally, on <u>day 4</u>, there will be:

---> 100 x 1.25 = 125 responses

A quicker way of getting this would be to do:

64 x 1.25³      since you are multiplying by 1.25  3 times

--------------------------------------------------

Answer:

125 responses

Find the greatest common factor
Lerok [7]

Answer:

(3b + 4) is the greatest common factor

Step-by-step explanation:

3b(2b- 3)+4(2b-3) = 0 \\  {6b}^{2}  - 9b + 8b - 12 = 0 \\  {6b}^{2}  - b - 12 = 0 \\  {6b}^{2}  - 9b  + 8b - 12 = 0 \\ 3b(2b - 3) + 4(2b - 3) = 0 \\ (2b - 3)(3b + 4) = 0
