(3) A frog in a well is 10 m below the ground level. It jumps 6 m and then falls back 4 m.
How far is it from the ground level?
(4). A submarine is 78 m below sea level. It rises 36 m and then dives 25 m. How far is it
below sea level?
5)

39m below sea level, what is the vertical distance between the helicopter and the
submarine? Above sea level 120m below. 39m
120 m - 39m

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.

i saw this question before, dont know the asnwer srry

step-by-step explanation:

the best estimate is 3 because   8 can only go into 24 3 times

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
