Answer:
56 music files
Step-by-step explanation:
From the above question:
Let the number of music files
Arely has = x
Valerie has = y
Arely has 4 fewer than twice as many music files as Valerie.
x = 2y - 4
They have a combined number of 86 music files.
x + y = 86
We substitute 2y - 4 for x in the above equation
2y - 4 + y = 86
3y - 4 = 86
3y = 86 + 4
3y = 90
Divide both sides by 3
3y/3 = 90/3
y = 30
Hence, Valerie has 30 music files.
The number of music files that Arely has is calculated as:
x = 2y - 4
x = 2(30) - 4
x = 60 - 4
x = 56
Arely has 56 music files
Answer:

Step-by-step explanation:
something about them being diagnol to each other makes them equal
havent done geometry in a while lol
hope this helps <3
Answer:
Option 1 is correct.
Step-by-step explanation:
Given two functions f(x)=sec x and g(x)=arcsin x
we have to find f(g(x)).
f(g(x))=sec(arcsinx)=sec A where A=arc(sinx)
As, A=arc(sinx)
⇒ 
⇒ P=x and H=1 gives 
hence, 
hence, 
Rationalizing, we get

Option 1 is correct.
Answer:
width=4
length=18
Step-by-step explanation:
length-6=3width
length=3width+6
also:
perimeter of the rectangle=2(length+width)
44/2=width+length
22=width+length
now put the length we found in the 1st equation, in 22=width+length
=>22=width+3width+6
22-6=4width
width=4
now do the exact same thing with one of these equations:
22=width+length
length=3width+6
I'd do it with the 1st one:
22=4+length
22-4= length
length=18
The circumference would be 6 inches because you do 3 times 2
