SHOW WORK

Step-by-step explanation:

-8+(-9) = -17  <--- Negative    If they are both negative, then you do the simple math part and then add the negative sign

7+(-3) = 4  < Positive    If there are only one negative, then you get rid of the '+' and then the equation turns into 7-3. You would do the simple math.

5+(-12) = -7 < Negative.    Here, there is only one negative sign but the negative number is greater than the positive number. So, you would do the math 5-12 and use the negative sign.

-12+5 = -7 < Negative   Look at the one above this.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
