487 rounded to nearest thousand

1,000

Step-by-step explination: Rounding to hundreds it would be 500, but because then number isn't in the thousands the closest it would be is 1,000.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
