Hi there!
Okay, so I was a bit confused by your question, but I tried to make it a bit easier and work out.
There was two ways I did this because I didn't want to NOT answer your question!
What about this:
3.2/15 cannot be simplified lower than what it is. Decimal form is 0.2133333 (repeating). I answered this part because I didn't know what 3. was (I at first thought it was part of the numerator. But now that I look at it again it may have been a question number. But just in case, I answered it like this anyway.)
Next!
I solved 2/15, which also cannot be simplified down lower than what it is. It's decimal form is 0.133333 (another repeating decimal.)
And so as you can see I answered two problems for you. If these are incorrect, let me know!
Hope this helps!
2x+y-3=0,x-2y=1 okay that's the answer good luck
Step-by-step explanation:
Given the Arithmetic sequence
An arithmetic sequence has a constant difference d and is defined by
as
∵
∵ 
∵ 
Therefore, the indicated nth partial sum of the arithmetic sequence is 1530.
ANOTHER METHOD
as
n = 30
as
and
so
