draw a 3 and atatch a backwards 3 to it.
8
8 of them, with 2 left over.
5s - 3 = 3s - 92s = -6s = -3
8
Each two 3s have different values because they are in different postion
-1
Place the first 3 on the left.Take the second three and flip it vertically (so the round parts are to the left, instead of to the right).Push the two numbers together to form the number 8.
8 of them, with 2 left over.
5s - 3 = 3s - 92s = -6s = -3
Each two 3s have different values because they are in different postion
Suppose the two who ran the same amount ran s miles each. The third person ran s - 8 miles So the total miles run is s + s + (s - 8) = 3s - 8 Now 3s - 8 = 64 So 3s = 64 + 8 = 72 So s = 72/3 = 24 The third person ran s - 8 = 24 - 8 = 16 miles.
(3+3) / .3
s = 4
You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6
The are two electrons in the 3s orbital of magnesium (Mg.)

8+8=16
