Answer:
DE = 15
DF = 23
Step-by-step explanation:
E___D___F
EF = DE + DF
38 = (3x +9) + (12x-1)
38 = 15x + 8
15x = 38 - 8
15x = 30
x = 30/15
x = 2
DE = 3x + 9 = 3(2) + 9 = 6 + 9 = 15
DF = 12x - 1 = 12(2) - 1 = 24 - 1 = 23
I hope I helped you^_^
23/2
If x = 5,
y = 5 + 1 = 6
(5+6) + 1/2 = 11 + 1/2 = 23/2
Answer: I'd assume its B 100 miles each day.
