Answer:
-6
Step-by-step explanation:
8x/3 - 2x/4 = -13
find the L.C.M
<u>32x - 6x </u> = -13
12
<u>26x </u> = -13
12
cross multiply
26x = -156
divide both sides by 26
26x/26 = -156/26
x = -6

Answer:
k = 10
Step-by-step explanation:
The sum of k terms of a geometric sequence with first term a1 and common ratio r is given by ...
... Sk = a1·(1 -r^k)/(1 -r)
For the given numbers, this is ...
... 118096 = 78732·(1 -(1/3)^k)/(1 -1/3)
Manipulating this to get the term containing k, we have
... 1 -(2/3)(118096/78732) = (1/3)^k
... 1/59049 = (1/3)^k
Taking logarithms, we get
... -log(59049) = -k·log(3)
... log(59049)/log(3) = k = 10
