Answer:
1. 15
2. -2
Step-by-step explanation:
First, since -4 is in parentheses, we want to take it out of parentheses. This might make sense but now it becomes 12 + 7 - 4. If it doesn't make sense, I'm sorry because I don't know how to explain it. Now we add 12 to 7 and we come out with 19. Then we subtract 4 and get 15. We want to do the same for number 2. We take -6.25 out of the parentheses and we have -1.75 - 6.25 + 6. When you subtract a negative something from a negative, we get more negative. So now we have -8 + 6. Which then equals -2. I hope this helps!

The total weight would be 5 lbs 12 oz.
Step-by-step explanation:
First, combine the ounces:
13 + 15 = 28 ounces
Next, convert that into pounds and ounces.
28 oz = 1 lb + 12 oz
Finally, add the weight back to the 4 lb.
1 lb + 4 lb + 12 oz = 5 lb + 12 oz
