To fill the 18 gallon gas tank in samantha's car, it cost her $49.1. find the cost per gallon

$2.73 per gallon.

Step-by-step explanation:

Divide 18 from 49.10 to find the unit rate.

49.10/ 18 = 2.7277... The seven is continued.

2.7277... is the unit rate.

The cost per gallon is $2.73

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)

thus, the first answer choice, y = sec x, is the correct one
