Okay so 3x + 3 - 244 = -238 so I think you would put -238 on the number line and then fill in the line to the negative spot I hope that helps
Since there are 16 oz in 1 lb, take 256, divide it by 16, and the answer is 16. Therefore both are the same because 16 lbs = 16lbs
The first is proportional the second is proportional and the third is not proportional
