Adam is scuba diving. He descends 6 feet below sea level. He descends the same distance 3 more times. What is Adam's final elevation?

-18 feet below sea level

Step-by-step explanation:

Take 6 multiply by 3 then turn into a negative

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.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
