1.01 LC)Look at the following numbers: − 4, −1, 0, 4 Which pair of numbers has a sum of 0?

-4 + 4

Step-by-step explanation:

It is -4 + 4 because if you imagine on a number line, you go left 4 (since it is negative) and add 4, so you go to the right 4, which leaves to 0.

Or, you can think of it like this:

+4 - 4

= 4 - 4

= 0.

I hope this helps. Sorry if I was wrong

the answer would be -4 and 4 thess two numbers has a sum of 0

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
