Answer:
165920160 ways
Step-by-step explanation:
Number of songs in library (n) = 115
Number of songs in Playlist (r) = 4
Since the order is important:
nPr = n! / (n-r)!
115P4 = 115! / (115 - 4)! = 115! / 111! = (115 * 114 * 113 * 112)
= 165920160 ways
Answer:
x = -5
Step-by-step explanation:
2/3x - 1/2 = 1/3 + 5/6x
add 1/2 to each side of the equation:
2/3x = 5/6 + 5/6x
subtract 2/3x from both sides:
0 = 5/6 + 1/6x
subtract 5/6 from both sides:
1/6x = - 5/6
multiply both sides by 6:
x = -5
