Answer 4

seems rigth

Answer 5

\[\frac{\text{ serves in } }{ \text{ serves out } } =\frac{\text{ a given serves in number }} {\text{ what would be the out number for that given in number }} \\ \frac{2}{4}=\frac{28}{x } \\ \text{ reduce right fraction } \\ \frac{1}{2}=\frac{28}{x} \\ \text{ flip both sides } \\ \frac{2}{1}=\frac{x}{28} \\ 2=\frac{x}{28} \text{ since } \frac{2}{1}=2 \\ x=2(28)\]

@jagr2713 you were on the right track
"ok for every 2 servers 4 land out.
so if he gets 4 serves 8 land out
so he gt 28 serves. So
/....
not the relationship was 4/2= and 8/4=2
so what number divided by 2 gives you 28
or what number=2*28

Answer 9

@s117 do you understand this answer ?

Answer 10

i apologize @S117

Answer 11

@jagr2713 As I said you were on the right track
like you noticed a pattern
I don't think you need to apologize
This is where the asker could have been like well every lands out number is double the in's number
