Which of the following show the Associative Property? A. 3 + 8 + 9 = 9 + 3 + 8
B. (3-8) - 9 = 3 - (8 - 9)
C. None of these
D. (3 + 8) - 9 = 3 + (8 + 9)

i used to know but i learned it a long time ago sorry

step-by-step explanation:

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.
