There are no real solutions
Answer:

Step-by-step explanation:
We are given the recursive formula:

This is the recursive formula for an arithmetic sequence.
The explicit formula for an arithmetic sequence is given by:

Where d=3 is the common difference.
We plug in this values to get:

We now expand and simplify to get:

We simplify to obtain:

Answer: x = 22
Step-by-step explanation:
We must isolate the x by itself.
We need to add 5 to both sides of the equation so it cancel out from the side with x.
So x = 22
Answer:
Step-by-step explanation:
80
If were talking about the second one it would be 8 mins because by the time 6 is down to 2 it would be 8 mins and since 10 fl oz is going down every 1 min it would be 2 fl oz by the time it is at 8 mins
