Which pairs of integers are additive inverses (opposites)? Select all that apply.
A and -10
B -9 and 9
c) 14 and 5
25 and -25
11 and -8

Your answeer choices arent exactly the clearest, but check my explanation for my answers.

Step-by-step explanation:

1. -9 and 9

2. 25 and -25

This is pretty simple math but the only way I can explain this is that positive's oppisite is negative. If you have a positive number ( 5 ) and need to find its opposite, you need to find the negative of 5, which is -5. Good luck!

P.S: I'm a 6th grader so be sure to use your common knowledge too.

PP.S: You can trust my 6-7th grade head because I have an 100 in math.

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21
