Answer:
Step-by-step explanation:
To find the nth term of a geometric sequence, you have the general formula:
where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):
135 = 
135 = 
135 = 
Now, we can substitute the first term back in:
Answer:

Equation=$140+$85=$225
Step-by-step explanation:
If she sold her bike for $140 less than she paid for it, and she sold it for $85, you add 140 to 85 to get out much she paid for. To check your answer do 225-140=85.
The value of the x is 120
Answer:
Step-by-step explanation:
make ? = y
4x-2+4(2x+y)=12x +14
distribute
4x-2+8x+4y=12x+14
group like terms
12x-2+4y=12x+14
the 12x cancels out on both sides
-2+4y=14
4y= 12
y=3
? = 3
