27.9km to the nearest km
yuradex [85]

Answer: It rounds to <u>28 km</u>

Explanation:

The units or ones digit is "7". The next digit over (9) is five or larger. This means we bump the 27 up to 28. Everything after the 7 is ignored.

So we could have something like 27.999871212512 and we still follow the same idea of focusing on the 27, bumping it up to 28, and everything else gets ignored.

The reason for this is because 27.9 is much closer to 28 than it is to 27. Draw out a number line to help see this. Split the region from 27 to 28 into 10 equal pieces. The 9th little piece represents 27 & 9/10 aka 27.9

Refer to the number line diagram below.

-x = -6 <br> please help me
Rasek [7]

Answer:

The answer would be positive 6

Step-by-step explanation:

I know it is -6 because when you solve this you do...

-x = -6

Divide both sides by -6

-x/-6 = -6/-6

the answer would be 6

because a negative divided by a negative is a positive.

Hope this helps have a great day! :)
