Hello :D
To work this out we need to look at the thousands column. After you find the thousands column, you look at the column on the right side of it. If that number is higher than 5, you round it up. If it is 4 or lower, then you round it down.
990687
Thousands = 0687
It has a 6 next to it you round it up. So the answer would be 991000. I hope this helps

120/15=8.
What that means is that for every 8 feet, there's 1 inch added to the scale drawing. Good luck!
Answer is 26 13/64
first u need to simplify mixed number then multiply them all
43/8*3*13/8=1677/64
So firstly, the three terms share a GCF of x, so factor that out: 
Next, I'm going to be factoring by grouping. But first, what two terms have a product of 140x^2 and a sum of 33x? That would be 28x and 5x. Replace 33x with 5x + 28x: 
Now factor 20x^2 + 5x and 28x + 7 separately, make sure that they have the same quantity on the inside: ![x[5x(4x+1)+7(4x+1)]](https://tex.z-dn.net/?f=%20x%5B5x%284x%2B1%29%2B7%284x%2B1%29%5D%20)
<u>Now you can rewrite the expression as ![x[(5x+7)(4x+1)]](https://tex.z-dn.net/?f=%20x%5B%285x%2B7%29%284x%2B1%29%5D%20)
, which is your final answer.</u>
