Answer:
Their are no possible factors for this expression.
Step-by-step explanation:
Number 7: 11/12-9/10 = 110/120-108/120=2/120= 1/60
number 8: 5/18-1/3=15/54-5/54=10/54 =5/27
855=95d
855 minutes is equal to 95 minutes times the number of days run
Answer:
C. 
Step-by-step explanation:
You can solve this in two ways, firstly by eliminating all the wrong answers, and secondly by just knowing that the horizontal line in 
means that we are talking about a line.
This is how we solve this question by using the eliminating process.
(A. ∠C) is not the right answer because the ∠ sign lets us know that this answer represents an angle, not a line
(B. <em>B) </em>is not the right answer because it represent a point, not a line (in math we use a singular capital letter to represent points)
(D. ΔABC) is not the right answer because the Δ sign lets us know that the answer represents a triangle, not a line.
Therefore, the only option left is C. 
the second one 6,6,6 it is a square all the others seem like a triangle
