Solve for x.
8x + 13
12x +7>>

As they are alternate exterior angles, so they must be equal.

8x + 13 = 12x + 7

8x - 12x = 7 - 13

- 4x = - 6

x = 3/2.

answer: 32.68

step-by-step explanation:

x=2

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.
