Verizon Plan A is $40 + $12 per gigabyte. Verizon Plan B is $30 + $14 per gigabyte. How many gigabytes would be needed to make the two plans equal?

Step-by-step explanation:

let no of gigabyte be x GB.

40 + 12x = 30 + 14x

10 = 2x

x = 5

therefore, 5 GB

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.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
