Answer:
There is not enough information to answer this problem.
Step-by-step explanation:
A proportional function means that if you change X, Y will change in the same proportion. And that proportion of change will remain the same no matter which two values of X you take to compare them.
But that proportion will vary from function to function.
Without knowing what the function is, it's impossible to know the value of Y for a given X... it could be anything.
3b=$9
let b be comic books
divide both side by 3 which gets you the answer of b=$3
2/3
4/3-one books, 2 nights
6/3-2 books, 3 nights
8/3
10/3-3 books, 5 nights
12/3=4 books in 6 nighs
It’s the 2nd on I’m pretty sure because it says decimal
Find the difference between the two times
= 4 2/5 - 2 1/4
convert each mixed number to an improper fraction
= 22/5 - 9/4
change to common denominator (20)
= 88/20 - 45/20
subtract numerators only
= 43/20
change back to mixed number
= 2 3/20
ANSWER: It took 2 3/20 hours longer to clean the bathroom.
Hope this helps! :)
