X is the center of the circle
Absolute value is always positive so I would say the answer would be A.
Answer: That number is 16.
Step-by-step explanation:
n + 7 = 2n- 9 n represents the number now solve the question
+ 9 +9 add 9 to both sides
n + 16 = 2n subtract n from both sides
-n -n
16= 1n Divide both sides by 1
n= 16
Check: 16 + 7 = 2(16) - 9
23 =23
