LOL 3 more to gooo . find the value of x

17

Step-by-step explanation:

These two angles add up to 180, so we can set up an equation. 5x-23+7x-1=180. Now we combine like variables, getting 12x-23-1=180. We add 23 to both sides, and get 12x-1=203. Then we add 1 to both sides, getting 12x=204. Finally we divide by 12 on both sides, with our result as x=17.

The value of q = 20

Step-by-step explanation:

x2−12x+q=0 is 2.Find the value of q = ?Substitute value of x =2 in the following  equation,(2)2 ₋ 12(2) +q= 04₋24 +q = 0₋20 + q= 0shifting ₋20 on the right hand side, the minus sign changesq = 20Therefore, value of q=20
