Answer:
The answer to your question is 12.5 %
Step-by-step explanation:
Data
Total points = 168
Points scored in the regular season = 147
Percent of points scored in the playoff game = ?
Process
1.- Calculate the points scored in the playoff game
Points in playoff game = 168 - 147
= 21
2.- Calculate the percent of points scored in the playoff game using proportions
168 points -------------------- 100%
21 points --------------------- x
x = (21 x 100) / 168
x = 2100 / 168
x = 12.5 %
Answer:
A: an = 6n - 9
Step-by-step explanation:
third term in an arithmetic sequence is 9
a3 = a + 2d
a + 2d = 9
the fifth term is 21
a5 = a + 4d
a + 4d = 21
a + 2d = 9 (1)
a + 4d = 21 (2)
Subtract (1) from (2) to eliminate a
4d - 2d = 21 - 9
2d = 12
d = 12/2
d = 6
Substitute d = 6 into (1)
a + 2d = 9 (1)
a + 2(6) = 9
a + 12 = 9
a = 9 - 12
a = -3
nth term of this sequence = a + (n - 1)d
= -3 + (n - 1)6
= -3 + 6n - 6
= 6n - 9
an = 6n - 9
