Answer:

Step-by-step explanation:
1) Simplify 1/3 ( x - 10) to x-10/3.

2) Multiply both sides by 3.

Simplify 4 × 3 to 12.

4) Add 10 to both sides.

5) Simplify -12 + 10 to -2.

So, therefor, the answer is, x = -2.
You can use the equation rise over Run you go up 4 and over 6 and you go down 2 and over 8 (im not sure if this helps)
If i remember correctly i think you just cross multiply <span />
5 486 814 rounded to the nearest thousandth so here this is 6th digit:
because 7th digit is 4 we round down:
548.6814≈548,681
Suplementary is angles add up to 180 degrees
C=180-D
C=180-84
C=96 degrees
Hope this helped :)
