Answer:
there are 8 blue socks
Step-by-step explanation:
28 / 4 = 7
multiply 2/7 by 4 and you get 8/28
2c - 5 < -21 - 2c |add 5 to both sides
2c < -16 - 2c |add 2c to both sides
4c < -16 |divide both sides by 4
c < -4
To get your answer we'll plug 0 in for x into the equation.
So, multiply 4*0 which equals 0.

Then we'll add 0 and 7 which leaves us with
The y-intercept of this equation is: 
To find the x-intercept of this equation we'll rewrite it as

Then we'll subtract 7 from both sides,

Now we'll divide each side by 4. Then simplify which brings us to our answer,
The x-intercept of this equation is:

C. 3.0 is the nearest mean
The slope of the given line is -6, so your perpendicular line will have slope 1/6. The point-slope form of the equation of a line can be used.
.. y = (1/6)(x -12) -3
This can be simplified to
.. y = (1/6)x -5
