1.) add 9 and 5 which is 14-6x
Answer:
212.5
Step-by-step explanation:
10=85
212.5=25
$20 bought 16 songs
Therefore each song costs $20/16 = $5/4 = $1.25
So:
2 songs would cost 2 * $1.25
3 songs would cost 3 * $1.25
...
x songs would cost x * $1.25
Since Renata started with $20, then her balance (y) after buying x songs would be:
y = 20 - 1.25*x
I’m guessing you want oh know what x and y are?
If so isolate the variable and do the inverse of the operation
If not please correct me ^^
