Wade wants to have at least $55 left, so the sign will be ≤ (greater than or equal to 55) One sweater costs $12. You can use x to represent an unkown number of sweaters, so $12x. You are subtracting 12x by your budget of $175. When put together, the inequality is $175-$12x ≤ $55. Now to solve. You want to get x alone so subtract 175. You must do this to both sides. Now you have -12x≤ -120. Divide both sides by -12 and your final answer is -120/-12 ≥ 10. (Notice the sign changes when you divide by a negative) So Wade cannot buy more than 10 sweaters to have $55 left over. Phoo that was a workout. It can be difficult but once you get the hang of it it comes easy. If you need more help just ask :D

X is the number of sweaters Wade buys.
175$-12x≥55$.
Solve the equation to get X = 10 sweaters.

Round 672,831 to the nearest ten thousand
Alik [6]
Well, you just have to take what I said before:

1=ones digit
3=tens digit
8=hundreds digit
2=thousands digit
7=ten thousands digit
6=ten thousands digit

So like previous answers, you just look at the digit after the one being asked

So look at the thousands place. 2,831 or 2,000 since all numbers after that digit is irrelevant

Is 2,000 or 2,831 over the halfway point to 10,000? The halfway point being 5,000

No, it is not so that means 2,831 is closer to 670,000 rather than 680,000

Answer: 672,831 rounded to the nearest ten thousand IS 670,000
