believe the answer is 8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.
In order to find the scale they are using first you must divide 12 by 3.75.
But since we get to estimate, the 3.75 will be made into a 4 because it's the whole number closest to 3.75.
12/4=3
Take your 3 inch scale and multiply it by 3 (we are using 3 instead of 2.8 because it's a whole number) to get the real life fence size.
3x3=9
The fence is about 9 feet.
3x + 5y = -2
3x + 7y = 26
Subtract first equation from second
2y = 28
y = 14
Plug it in
x = -24
