2. Write two numbers that are opposites and each more than 6 units away from 0.
Yuki888 [10]

Answer:

-7, 7

Step-by-step explanation:

Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)

Cole said that 555 rounded to the nearest ten is 600. What's coles error?
ki77a [65]
Cole's mistake was that he rounded 555 to the nearest hundred instead of the nearest ten. He should've rounded it to 560 because the tens place is the second number, not the first one.
