In order to subtract one fraction from another, we need to make the denominator the same in both fractions. The lowest common denominator is 8, because 4 is a factor of 8.
In order to make the denominators the same, multiply both the numerator and denominator of 13/4 by two. This keeps the value of the fraction the same, but will equate the denominators.

At this point, we can simply subtract 5/8 from 26/8.

21/8 cannot be simplified, so it is the answer.
Step-by-step explanation:
5z, 5x and 5y are all unlike terms.
If there was something like <em><u>5z</u></em> + 5x <em><u>-</u></em><em><u> </u></em><em><u>3z</u></em> + 5y, then both 5z and -3z have something in common and so therefore are said to be like terms.
Hope my description helps.
Good night.

Answer: 55</h3>
==============================================
The 125 degree angle and angle 6 are supplementary. This is because of the same side interior angles theorem.
Let x be the measure of angle 6. Add this to 125, set the sum equal to 180, and solve for x.
x+125 = 180
x = 180-125
x = 55
------------
Or you could approach it this way:
y = measure of angle 2
y+125 = 180
y = 55
angle 6 = angle 2 (corresponding angles)
angle 6 = 55 degrees
-------------
Yet another way you could solve:
z = measure of angle 3
z+125 = 180
z = 55
angle 6 = angle 3 (alternate interior angles)
angle 6 = 55 degrees
A similar approach using alternate interior angles would involve angle 5 = 125, and then noticing that x+125 = 180 solves to x = 55
