ally’s answer is sometimes true. -6.2+5.71=-11.91 5.71+-6.2=11.91 5.72-2.84=2.99
3x=18 because you add the like terms 6 and 12
Answer:
option B
Step-by-step explanation:
9/10 + 6/5 + 3/2...........
We find the difference between the terms


We will get the same difference when we subtract consecutive terms.
so , d= 3/10, a= 9/10
we find the formula for nth term
a_n = a+(n-1) d




we need to find eighth partial sum so we take n=1 to 8
sum of 8 terms (
)
So option B is correct
Get the app called Photomath. It should help with this:)
