Attached the solution and work. I think this is what you asked for.
Answer:
n = 5
Step-by-step explanation:
First, you'd want to expand the entire equation to solve it.
4 (2n + 5) = 60
8n + 20 = 60
8n = 40
n = 5
I hope this helped!
That's how I would graph it...
Answer:
n = -2, not 1
Step-by-step explanation:
You made a mistake in your work.
When you get your final answer to convert to scientific notation, you should get 0.018166. The value of n in the scientific notation would then have to be -2.
