E. 54

Answer 1

@Nnesha

Answer 2

q =s =4r
so you can substitute q and s for 4r

Answer 3

q = 4r
s = 4r
q=s

Answer 4

can i substitute numbers from the choices to r?

Answer 5

well you can solve for r that would be easy
but yea you can :=)
\[\huge\rm \color{ReD}{q} + r + \color{ReD}{s} = 117\]
\[\huge\rm \color{ReD}{4r} + r + \color{ReD}{4r} = 117\]

Answer 6

why did you leave r single?

Answer 7

given is ` q = s = 4r solve for r`
we have to solve for `r`

Answer 8

okay thank you. I have another question. can you help?

Answer 9

i will try
