(5x-2) + (2x+6) = 67, so we simplify and solve for x:
7x + 4 = 67 --> 7x = 63 --> x = 9
Now we substitute 9 for x in (5x-2):
5(9) - 2 --> 45 - 2 = 43
The distance between A and B is 43 miles.

Answer:
3.4 Hours
Step-by-step explanation:
25 x $7.75 = $193.75
$250 - $193.75 = $21.25
$21.25/$6.25 = 3.4 hours
You must work 3.4 hours at the second job.
Answer:
Step-by-step explanation:
In order to write the equation of this line, we need to pick 2 points on the graph where the line goes right through the intersection of the grids. Actually, you only need 1 of these, because the line goes through at (0, 15). Another point then can be (6, 6). Locate this point so you know what I means when I say that the line goes right through where the grids intersect at x = 6 and y = 6 (as opposed to somewhere in the middle of one of these grids). Find the slope between these 2 points:

Since there's only one choice with that slope, that is the choice you want.

Multiply and divide by the conjugate of the denominator, which is

The numerator is a square of a sum, and the denominator is the product of a difference and a sum (product of two conjugates). Then, expand the common products:
