X is the number of songs and Y the number of pics
1:X+y=11
2:4x+2y=24
1: x=11-y
Lets replace x in 2:
4(11-y) +2y=24
44-4y+2y=24
44-24= 4y-2y
20= 2y
Y=20/2
Y=10
Lets replace y in 1
X+10=11
X=11-10
X=1

A = 4πr² Divide both sides by 4π
A / 4π = r² Find the square root of both sides
√(A / 4π) = √(r²) Cancel out the square with the square root
√(A / 4π) = r Switch the sides to make it easier to read
r = √(A / 4π)
It would be C because you have the sum will equal 60 so you would add the two amounts together and then add r to find if he has enough room. (Which he doesn't... I think)
