Necesito ayuda con esta operación combinada, necesito la cuenta hecha..40:(-8)-3.(5-16-2.5)+100=

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.

47 - 90 = 43

43 - 180 = x

x = 137

the diver is 33 feet below the surface.

step-by-step explanation:

hope this
