If n-2 = 1/16, then n could be which of the following?
a.-8
b.-4
c.-1/4
d.1/4
e.4

Option B and E are correct

n could be 4 and -4

Step-by-step explanation:

Given the following:

we know that:

Then;

By cross multiply we have;

or

⇒

Simplify:

⇒n = -4 and n = 4

Therefore, n could be 4 and -4

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.

the answer is c)8
