What’s the answer 6x=4x+140
dmitriy555 [2]
1) given 6x = 4x + 140

2) subtract 4x from both sides => 6x - 4x = 4x - 4x + 140

=> 2x = 140

3) divide both members by 2 => 2x / 2 = 140 / 2

=> x = 70

4) Answer: x = 70

Find the sum of the geometric sequence –3, 15, –75, 375, … when there are 9 terms and select the correct answer below.
zavuch27 [327]
Sn=sum of the n terms of the geometric sequence.
a= the first term
r=the common ratio
n=numbers of terms.

Sn=a[(1-r^n)/(1-r)]

In this case:
a=-3
r=a₂/a₁=15/-3=-5
n=9

S₉=-3[(1-(-5)⁹) / (1-(-5))=
S₉=-3(1+1953125)/6)=
S₉=-3(1953126/6)=
S₉=-3(325521)
S₉=-976563
