This problem involves a limit and the greatest integer function. My current guess is B. 1/3.5. I plugged 3.5 in for x. My numera

tor became 1.5, but I rounded down to 1 because it is the greatest integer function and ended up with 2/7 or 1/3.5

Yes your<span> answer is correct. Nice job.</span>

You should get 1 in the numerator when you plug in x = 3.5 and evaluate/simplify
In the denominator is simply 3.5

So you'll have 1/3.5 = 1/(7/2) = 2/7 as the final answer

1/2(7x-8)+2x =2-(10x+4
geniusboy [140]
<span>1/2(7x-8)+2x =2-(10x+4)
Distribute
(7x-8)/2 + 2x = 2 -10x -4
combine like terms
(7x - 8)/2 + 2x = -10x - 2
Multiply both sides by 2
7x - 8 + 4x = -20x -4
Combine like terms
11x - 8 = -20x - 4
add 8 to both sides
11x = -20x + 4
add 20x to both sides
11x + 20x = 4
combine like terms
31x = 4
divide both sides by 31
x = 4/31 or </span><span>0.129.

Hope this helps :)</span>

Talja [164]

Answer:

31 hours

Step-by-step explanation:

To at least buy the Air-Pods she will need to work at least 31 hours. You can either round at the beginning or end, I'll demonstrate rounding at the end.  Divide $278.10 by $9.00, getting 30.9. You would have to round up to insure you have enough money, getting 31 hours
