We need to look at the first clue, which is that they are 12th graders.
Add all the numbers in the 12th grade row and you get 68
Then match up the 12th grade row with the math column and the number presented you put over 68 so 28/68
Divided and you get D
X= 1, x = 5
-3|x - 3| = -6
———— —– divide both sides by -3
-3 -3 and remove the bars
x - 3 = 2
+3 +3
—————
x = 5⭐️
-3|1-3|➡️-3|-2|= -6
Answer:
x = 100°
Step-by-step explanation:
in the given figure
(x + 23°) + 57° = 180°
(they form linear pair)
- x + 23° + 57° = 180°
- x + 80° = 180°
- x = 180° - 80°
- x = 100°
Answer:
-1/20
Step-by-step explanation:
r/2 + s/r - r/4 + 1/5 =
= -1/2 + 0/(-1) - (-1)/4 + 1/5
= -1/2 + 1/4 + 1/5
= -10/20 + 5/20 + 4/20
= -5/20 + 4/20
= -1/20
