Answer:
where are the numbers Pls... provide them
Answer:
I think you put that } by accident so if its 4+2y=6
your answer is y=1
F (x)=(x+4)/6
f-1 (7)=x
f (f-1 (7)=f (x)
7=f (X)
7=(x+4)/6
x+4=42
x=38
You take 60x.4 to see you are left with 36 inches 24x.75 to see what 75% of the 40% cut off is and you see she only needed 18 so you add back the Extra 6 cut off to the leftover 36 and you have 42 inches of ribbon left
