At the beginning of a laboratory experiment, the temperature of a substance is -12.6 C. What is the final temperature of the substance?

look a the sides they are perpendicular

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.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
