1/4 of 12 simply means that if there are 4 equal quarters in 12, how many would be in each of those quarters, or 1/4*12 or 12/4. 12 divided by 4 means that the 12 is on the top and 4 is on the bottom, meaning 12/4.
Hi, I was wondering In what context was this question?
I think the answer is D. Sorry if it is wrong
Answer:
x = 1.5
Step-by-step explanation:
Solution
- log(4x - 1) - log(x+1) = log2 log(x + 1) was subtracted from both sides
- log[(4x - 1)/log(x+1)] = log2 Subtaction of logs means division
- (4x - 1) / (x + 1) = 2 Take the antilog of both sides
- 4x - 1 = 2(x + 1) Remove the brackets
- 4x - 1 = 2x + 2 Add 1 to both sides
- 4x = 2x + 3 Subtract 2x
- 4x - 2x = 3
- 2x = 3 Divide by 2
- x = 3/2 Answer
Check
<em><u>Left Hand Side</u></em>
- log(4*1.5 - 1)
- log(6 - 1)
- log(5)
<em><u>Right Hand Side</u></em>
- log(1.5 + 1) + log(2)
- log(2.5) + log(2)
- log2*2.5
- log 5
And they check
