Answer:
0.525 km
Step-by-step explanation:
divide length value by 1000
We are told that the first term is 2. The next term is 7(2) = 14; the third term is 7(14) = 98. And so on. So, the first term and the common ratio (7) are known.
The nth term of this geometric series is a_n = 2(7)^(n-1).
Check: What is the first term? We expect it is 2. 2(7)^(1-1) = 2(1) = 2. Correct.
What is the third term? We expect it is 98. 2(7)^(3-1) = 2(7)^2 = 98. Right.<span />
Answer:
The answer is B.
Step-by-step explanation:
Hi!
<h3>We need to isolate x on both sides, and whatever we do to the equation we have to do to both sides. </h3><h3>First, add 8 to both sides. </h3>
2x - 8 + 8 = -6 + 8
2x = 2
<h3>Divide by 2 on both sides</h3>
2x/2 = 2/2
<u>x = 1</u>
<h2>The answer is x = 1</h2>
Hope this helps! :)
