The second option, 7 rolls of quarters and 4 rolls of dimes.
7*10=70
4*5=20
70+20=90
Y=amount of money paid. (in $)
x=number of songs download.
We have this function:
y=0.25x+9.99
Then:
if y=113.74
113.74=0.25x+9.99
0.25x=113.74-9.99
0.25x=103.75
x=103.75 / 0.25
x=415
Answer: the number of songs downloaded would be 415.
Answer:
5x²(2y + 5)
Step-by-step explanation:
10x²y + 25x²
to start we have to express the parts of the function as multiplication
2*5*x²*y + 5*5*x²
then we have to see that they have both parts of the sum in common, and what they have in common we get out of common invoice and what is left we add together.
5x²(2y + 5)
