answer:
9/11
Step-by-step explanation:
(12-3)/(6-(-5))=9/11
This is a geometric sequence, so use the formula for the sum of a geometric sequence:
Sum = (a(r^n - 1))/(r - 1)
where a is the first term, -5
r is the common ratio, 5
and n is the number of terms
Thus,
Sum = ((-5)(5^6 - 1))/(5-1) = -19530
Hope this helps!
28 - 13 = 15
15 x 12 = 180 Fifth graders
They are not equivalent, try adding in numerical values for x, both do not come out the same.
