Answer:
If you look at the picture from my point of view it would be the top left box and the top middle box. Both have 10 boxes in them and you need three shaded in for half of that box, so if you have 10 boxes you will need 6 shaded in. Hope this helped.
Step-by-step explanation:
80
You have to add all of the numbers together and divide them by how many numbers there are.
95 + 67 + 43 + 115 = 320
320 / 4 = 80
+4
any opposite of a natural number is created with a "minus"
- (-4) = +4
