Answer:
1st problem:
Converges to 6
2nd problem:
Converges to 504
Step-by-step explanation:
You are comparing to 
You want the ratio r to be between -1 and 1.
Both of these problem are so that means they both have a sum and the series converges to that sum.
The formula for computing a geometric series in our form is
where
is the first term.
The first term of your first series is 3 so your answer will be given by:

The second series has r=1/6 and a_1=420 giving me:
.
Answer:
76.75
Step-by-step explanation:
83.5 + 70= 153.5
153.5 / 2 = 76.75
Your grade would be 76.75.
HOPE THIS HELPED
Theres not enough information??? I'd love to help tho
To solve equations, all we must do is isolate the variable and simplify. In this case, we need to get rid of the "/7" because it i with our "e." To do this, we should do the reverse operation of "/7" on both sides, and them simplify.
-5=e/7
*7 *7
-35=e
Using the math above, we can see that e=-35.
