Answer:
32 tickets.
Step-by-step explanation:
First, 1/3 of 48 is 16. So 48-16= 32. Usually, people think the remaining half is half of 48, but it's supposed to be half of 32. So half of 32 is 16. So Kacey used 32 tickets for those 2 games.
Answer:
-1049
Step-by-step explanation:
Take the first number in the sequence: -26
Find the common difference (what is the rule) : -11
Then plug it in like such
first number in the sequence + (term you are trying to find -1) times the difference or rule
So: -26 + (94-1)-11
order of operations :93 times -11= -1023
-26 + (-1023) = -1049
