How much must be added to 750 metres to make 2 km​

1250 meters because 2 km is 2000 meters

2000 - 750

= 1250

you need to add 1250 to 750 in order to make 2 km

Step-by-step explanation:

We know that:

1 KM = 1000 meters

and out of those 1000, we already have 750, therefore:

1000-750 = 250

Which completes 1 km now, since there are 2 km, add 1000 to 250:

1000+250 = 1250

So you need to add 1250 meters to make 2 km

Hope this helps!

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
