1/2a - 7 + 1/2 a = 1/3
1/2a + 1/2a = 1/3 + 7
2/2a = 22/3
a = 22/3
Answer:

Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept.
Parallel lines:
When two lines are parallel, they have the same slope.
8x-2y=7
Placing into the format, we have thtt:


Slope of 4.
This means that the desired line has the following equation:

Point of (12,1)
This means that when 
We use this to find b.



So, the line has the equation:

Answer:
y=x-7
Step-by-step explanation:
chose a set off of the table and then insert them for x and y then solve
EX.
2=9-7
2=2
this is correct.
A HEXA=6, gon, has 6 sides, and we know the perimeter, all sides added up, is 70, so one side is just 70/6, or 35/3
