Answer:
What are you subtracting 25 from?
Answer:
Read below for each answer! (^-^)
Step-by-step explanation:
1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.
2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.
3: 7. That's the greatest number both can divide into it.
4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.
5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.
Hope this helps!
