Answer:
1/4
Step-by-step explanation:
8-4/13-(-3)=4/16=1/4
A. 9(x+8) = 12(x+4)
B. 9x+72 = 12x+48
24=3x
x = 8
Julie bought 16 books (x+8), and Sandy bought 12 books (x+4).
This is a geometric series. The first payment represents the first term, a. The number of times he wants to pay back for subsequent payments represent the common ration, r. The first 30 payments represents the number of terms to use in finding the sum, n.
Hence, a = $ 200, n = 30 and r = 1.2.
The sum of a geometric sequence is given as:
Sn = (a((r^n)-1))/(r-1)
=<span>(200((1.2^30)-1))/(1.2-1)
= $ 236, 376. 31
</span><span>Explain why this series is convergent or divergent.
</span>Since the common ratio, r, is greater than 1, the series is divergent
