Answer:

x = 2

Step-by-step explanation:

log27(x + 7) - log27(x - 1) = ⅔

log27[(x + 7)/(x - 1)] = ⅔

(x + 7)/(x - 1) = 27^⅔

(x + 7)/(x - 1) = 9

x + 7 = 9(x - 1)

x + 7 = 9x - 9

8x = 16

x = 2

Which of the following rational numbers is equal to 3.4? (line above the four)
Travka [436]
Hey there! :D

So, we can just divide all the numbers to figure it out. 

31/9= 3.44444444

32/9=3.5555556

33/9= 3.66666777

34/9= 3.777778

The closest number to 3.4 is 31/9. "A" is the correct answer. 

I hope this helps!

You are thinking of withdrawing all your funds; $45,000 from your 401 (k) at age 54. The normal tax rate for you would be 28%. T
Ivan

Answer:

you don't save any money, you lose money instead

Explanation:

Given,

At 54, there is a tax rate of 28%

At 59½ there is a penalty of 10% with the tax rate of 28%

Therefore at 54, money left after tax = $45000*(1-0.28)=45000*0.72=$32400

At 59½, money left after tax =$45000*(1-0.10)*(1-0.28)= 45000*0.90*0.72=$29160

Money lost =29160-32400= -$3240
