Which of the following could be used to evaluate the expression -6 ( 4 2/3) ? a (-6) (4) + (-6) 2/3 b: ( -6 ) (4) x (-6) 2/3 c: ( -6+4 ) + (-6+ 2/3) d: (-6+4)x (-6+ 2/3)

-6 (4 2/3)

-6 * (4 + 2/3)

-6 *4 + -6 * 2/3

Choice B

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.
