Answer:

7k

____________________________________________________

Step-by-step explanation:

We are trying to combine like terms with the expression: -k - ( - 8k)

We are pretty much solving it.

Solve:

-k - ( - 8k)

The "- ( -" turns into a plus sign.

So it would look like:

-k - -8k or -k + 8k

Now, you would finish solving

-k + 8k = 7k

Can someone please do this for me?
san4es73 [151]

Answer:

64°

Step-by-step explanation:

<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>

x + x = 180

<em>Now one of these angles is 6 greater than half:</em>

x + (x/2 + 6) = 180

<em>Then we will solve for x:</em>

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

\frac{3}{2}x = 174

x = 116

<em>Plug it back in:</em>

x + (x/2 + 6) = 180

         /\

     x/2 + 6

   (116)/2 + 6

        64

<em>To check:</em>

116 + 64 = 180 ✓
