The two angles are supplementary angles, which when added together equal 180 degrees.

6x -10 + 6x +10 = 180

Combine like terms:

12x = 180

Divide both sides by 12:

x = 180/12

x = 15

The answer is C) 15

A line on the coordinate plane passes through the points (7, -5) and (3, 11). A line that is perpendicular to the first line pas
yulyashka [42]
Slope of the line passing through (7,-5) and (3,11) =
\frac{11 - ( - 5)}{3 - 7}
= -4

As two lines are perpendicular to each other, so when their slopes are multiply by each other, the answer will be -1

so the slope of the line passing through (-3,-9) and (5,n) will be
\frac{1}{4}
So will will get a formula below
\frac{n - ( - 9)}{5 - ( - 3)}  =  \frac{1}{4}
and the answer will be n=

Show work for this fraction equations 30 1/2 -13 3/4
loris [4]
30\frac12-13\frac34

Let's put these as improper fractions.
30 = 60/2. add the 1/2 to get 61/2
13 = 52/4. add the 3/4 to get 55/4

\frac{61}2-\frac{55}4

To add/subtract fractions, they must have the same denominator. (bottom no.)
If we multiply the top and bottom of a fraction by something, it stays equal.
We can conclude that 61/2 = 122/4. (bottom multilpies by 2, so does the top)

\frac{122}4-\frac{55}4

Now that we have a common denominator, we can subtract.
The "fourths" just sort of acts like a unit. Subtract 55 from 122 to get \frac{67}4.

We can convert this to an improper fraction simply by dividing 67 by 4.
This leaves us with 16, and a remainder of 3. Our answer is \boxed{16\frac34}
