Step-by-step explanation:
Answer:
Taking that you didn't provide any other information about the values of x..
The only plausible answer, which probably isn't your case but still can be valid out of context is 19.
Step-by-step explanation:
"X" is 10 in Roman numbers.
9 + 10 = 19
(But I suppose that you had more details to the question that you didn't yet share :) )
OR.. the answer might be an algebraic expression..
<u><em>"9+x" years old.</em></u>

Answer:
Downloading 28 songs will cost $26.64.
Step-by-step explanation:
Given that a brand-new music service is offering specials on individual song downloads, and the cost is $ 0.74 for each song up to 20 songs per month, and the cost doubles to $ 1.48 per download for any number of downloads over 20, to determine how much would it cost to download 28 songs the following calculation should be performed:
(20 x 0.74) + (8 x 1.48) = X
14.8 + 11.84 = X
26.64 = X
Therefore, downloading 28 songs will cost $ 26.64.
