Answer:
3.75 < n
Step-by-step explanation:
n + 7 < 5n - 8
Add 8 to both sides
n + 7 + 8 < 5n
n + 15 < 5n
Subtract 'n' from both sides
15 < 5n - n
15 < 4n
Divide both sides by 4
< n
3.75 < n

Answer: -3
Step-by-step explanation: To subtract the integers -15 - (-12), it's important to understand that when we have minus a negative, we can change it to plus a positive so -15 - (-12) becomes -15 + (+12).
So starting at 0 on our number line, -15 moves us 15 units to the left and +12 moves us 12 units back to the right and we end up at -3.
So -15 - (-12) or -15 + (+12) is -3.
