Answer:
1:3
Step-by-step explanation:
The question is asking what the ratio of jump ropes to students is.
The order of the question matters.
Since they ask for the jump ropes first and then the students, we
get a ratio of 18:54.
Find the GCF (Greatest Common Factor)
The GCF is 18.
Divide 18:54 by 18.
18/18=1
54/18=3
The answer is 1:3.
Answer:
2
Step-by-step explanation:
2 is a value of x that would not make the set a function because a function can't have multiple coordinates wit hthe same domain (x-coordinate). 2 is a domain that has already been used in the point (2,7). If this is used in (x,5), the point would become (2,5) and repeat a domain.
Note:
The x-coordinate could also be 1 or 6 because they have been used as domains as well.
Hope it helps!
