Answer:
20.1168 meters
Step-by-step explanation:
Variables:
cost of 1 hot dog = x
cost of 1 hamburger = y
Set up a system of equations and use substitution
x + y = 2.75
x + 7y = 11.75
x + y = 2.75 can be rewritten as y = -x + 2.75
x + 7 (-x + 2.75) = 11.25
-6x + 19.25 = 11.25
-6x = -8
x = .75
plug x back into other equation to find y
y = -.75 + 2.75
y = 2.00
1 hot dog = $0.75
1 hamburger = $2.00

1 for both
Answer:
(x) = 2x + 12
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = 
x - 6 ( multiply through by 2 to clear the fraction )
2y = x - 12 ( add 12 to both sides )
2y + 12 = x
change y back into terms of x with x = (x) , then
(x) = 2x + 12
