Answer: A
Step-by-step explanation:
The sum to infinity of a geometric series is
S (∞ ) = \frac{a}{1-r} ( - 1 < r < 1 )
where a is the first term 8 and r is the common ratio, hence
S(∞ ) = {8}{1-\{1}{2} } = {8}{1}{2} } = 16
Answer:
1. 2 × 10⁵
2. 8 × 10⁴
3. 9 × 10⁸
4. 1 × 10¹⁰
Step-by-step explanation:
Okay
5.
m+4=17
-4 -4
m=13
6.
12=24-y
24-12
y=12
7.
15-b=12
-12 -12
b=3
8.
10t=90
90/10
t=9

22/y=2
22/2
y=11
10.
54=6b
54/6
b=9
Answer:
C. x = 3
Step-by-step explanation:
Step 1:
- 6x + 19 = x - 2
Step 2:
- 7x + 19 = - 2
Step 3:
- 7x = - 21
Step 4:
21 = 7x
Answer:
3 = x
Hope This Helps :)
Answer:
I believe its B, But I am unsure since I haven't done geometry in a couple years.
