Keith_Richards [23]

Answer: 10 CD's

Step-by-step explanation:

Given

Tom can burn a CD in $\frac{4}{5}\ \text{of an hour}$

If he has 8 spare hours in the week, he can burn

"Help Me Please Fast"

Simora [160]

1st one: only mentions 1 p wrong
2nd one: saving means (-) cost so this is also wrong
3rd one: how much you owe is x-y and there is no (-) sign in there so it is wrong

the answer is the 4th one because it has p+14%p if p=price and 14%p=14% of p tax

If a sequence contains only whole numbers, which of these sequences could include the term 27?

erik [133]

Depending on the first term, the sequences
$a_n=2a_{n-1}+1
\\
\\a_n=3a_{n-1}
\\
\\a_n=a_{n-1}+6$
would work.

If the sequence began at 6,
$a_n=2a_{n-1}+1=6, 13, 27, ...$

If the sequence began at 1,
$a_n=3a_{n-1}=1, 3, 9, 27, ...$

If the sequence began at 3,
$a_n=a_{n-1}+6=3, 9, 15, 21, 27, ...$
