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
The coefficient of the variable in the expression 4-3x-7+6 is 3
<h3>
Answer: 6</h3>
=======================================
Work Shown:
a÷6 = 1
6*(a÷6) = 6*1 ... multiply both sides by 6
(6a)÷6 = 6
(6÷6)a = 6
(1)a = 6
a = 6
--------------
Check:
Replace 'a' with 6 and we see that,
a÷6 = 1
6÷6 = 1
Which is a true statement. Dividing any number but zero over itself is always 1.
