The table shows a linear function :)
3/4 put into eighths would be 6/8. So Mia would be able to make 6 batches with the butter that she has.
Answer:
This is an independent event, as the marble is put back into the bag. If it were removed completely, it would be dependent.
Answer: 13 (and Sally will always be 3 years older than Jill)
Step-by-step explanation:
Let S and J stand for Sally and Jill's ages. We are told:
- (S-5) = (J-5)+3 [Sally is 3 years older than Jill was <u>5 years ago</u>] The 5 years ago is the reason for the (S-5) and (J-5) expressions.
If Jill is 10, how old is Sally?
(S-5) = (J-5)+3
(S-5) = (10-5)+3
S-5 = 8
S = 13
We actually don't really need an equation for solving this, other than the question asks us to write one. It doesn't matter how many years later, since Sally is 3 years older, she will always remain 3 years older, if we ignore the likelihood that the statement doesn't hold true for the period between their actual birthdays.
