D - 10
if u add them all up it needs to equal 180°
Answer:
3 <= x <= 8
Step-by-step explanation:
A number is denoted as an arbitrary variable, let's call it x.
We have a double inequality:
1. No more than 8 means less than or equal to 8
2. No less than 3 means greater than or equal to 3
3 <= x <= 8
10x^2-10x+20 is the answer to this
Answer:
B
Step-by-step explanation:
It's easier to explain why the other 3 are wrong.
A is wrong because it is just a standard arithmetic sequence. It adds one every time. That WOULD be correct if it had started at 2, seeing as that is how much it costs to get the bike initially.
C is wrong because although it starts at 2 it adds 2 every hour. It should add 1 instead.
D is wrong because the price is the exact same. It means there is no additional cost for the subsequent hours.
