Can you show how to do 67,000 rounded to the nearest ten thousand on a number line.

On your number line have 60,000 and 70,000 and then 67,000 in its relevant place (just over halfway) and then show that it would be closer to 70,000 
Hope this helped :)

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
