Answer: 10 CD's
Step-by-step explanation:
Given
Tom can burn a CD in 
If he has 8 spare hours in the week, he can burn

There is no way of solving that unless we are given more information. Are ABC and DBC supplementary angles? If so, then m<DBC equals 70.
Answer:
y = x - 7
Step-by-step explanation:
You take each equation and sub in for x and y.
The first equation would look like this:
16 = 2(23) - 30 Then you answer looks like this:
16 = 16 but if you did that for the second set in the column it looks like this:
18 = 2(25) - 30
18 = 50 - 30
18 = 20 which does not equal canceling the first answer.
And the second answer doesn't make sense because if x > y you shouldn't add to x. The same goes for the third answer.
So that leaves only one answer y = x - 7
Hope this helps
Sorry if this answer is long

9/50 is the answer I think!
I converted 9/10 to decimal to make it easier for me to solve and got 0.9
I divided 0.9 by 5 and got 0.18
I converted 0.18 to fraction and got 9/50
