Answer:
a₈ = - 10935
Step-by-step explanation:
the nth term of a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
here a₁ = 5 and r =
=
= - 3 , then
a₈ = 5 ×
= 5 × - 2187 = - 10935
You would have ran 1,200 meters
A unit rate where one is in the Denometer, so you would want to divide the bottom by 10.
To add/subtract fractions you need to have a common denominator...
(2/2)(4n/15)+(5/5)(n/6)
8n/30+5n/30
(8n+5n)/30
13n/30
<span> You must make it a fraction by multiplying by 100, moving the decimal over by 2 spaces right so we have 36. Then, put it over 100, because it is a fraction. Now, with 36/100 we must simplify by dividing each number by another # that goes into it evenly, such as 2. We get 18/50, reduce by 2, we get 9/25. There you go hope I helped </span>
