Step-by-step explanation:
Yes, they can have both positive and negative oxidation numbers.
Scince the sum of a triangle is 180° just subtracts 180 from 67 which should be 113
Answer: 
Step-by-step explanation:
Slope-intercept form: y=mx+c (i) , of linear equations, m= slope and c= y-intercept of the line.
6x+7y=13in slope intercept form would be :

Comparing to (i) , 
Slope of parallel lines are equal.
So, slope of required line = 
Equation of line with slope m and passes through point : 
So, equation of required line:

Answer:
x=2.5
Step-by-step explanation:
First, you do 5 divided by 2, because you are trying to find a missing factor. After that, your answer, which is 2.5, is what x equals.
Hope that helps!
