Answer:
Step-by-step explanation:
<em>Let the number be x </em>
So,
=> The sum of number and 15 is x + 15
=> Three times will be 3(x+15)
<u>Given that</u> it equals 24
<u>So, the given condition is:</u>
3(x+15) = 24
<em>Resolving Parenthesis</em>
3x + 45 = 24
<em>Subtracting 45 to both sides</em>
3x = 24 - 45
3x = -21
<em>Dividing both sides by 3</em>
x = -7
Answer:
211*10⁹
Step-by-step explanation:
Total songs = 3country + 6pop + 7 disco + 3hip-hop = 19 songs
Max pop songs = 3
Case 1: no pop songs;
¹³C₁₀*⁶C₀= 286
Case 2: 1 pop song ;
¹³C₉*⁶C₁= 4290
Case 3: 2 pop songs;
¹³C₈*⁶C₂= 19305
Case 4: 3 pop songs;
¹³C₇*⁶C₃= 34320
Total = 58201
so, now if order is also to be considered for making playlists then the number of playlists is =58201*10! = 211*10⁹
