Answer:
A
Step-by-step explanation:
The segment BC joining the midpoints of 2 sides of the triangle is
Half the length of the third side, that is
x + 31 = 2(x + 19)
x + 31 = 2x + 38 ( subtract x from both sides )
31 = x + 38 ( subtract 38 from both sides )
- 7 = x → A
The answer is −3.555555555555556 but you can just put -3.55
Your thinking of the number 69
400-5x greater than or equal to 250
-400. -400
———————————————————-
-5x greater than or equal to -250
——. ——
-5. -5
X is less than or equal to 50
