Which of the lines, if any, are parallel

a and c are parallel.

Step-by-step explanation:

Let's find slope for each line.

If slopes of lines are same then they are parallel.

for line described by a : slope = = 1

For line b slope = = 2

For line c slope = =1

So slope of lines a and c are same. a and c are parallel to each other.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
