Step-by-step explanation:
slope is 4 y is 3
There are 11 full tables, because when you divide 138 by 12 you get 11 remainder 6. So there is 11, because 12 people are at 11 tables and 6 at one!
What I did for this question is I set up ans equation. 5x-7 + 3x+11 = 180 and I added the Xs and and I added 11 to -7. Then I got 8x+4=180. I then "-4" on both sides and then divided 8 by 176. Getting X as 22. We now know X and we put 22 into the equation for D which is "3x+11" getting 77 degrees. Hope this helped!
