Answer:
C. 16
Step-by-step explanation:
The distance between two points on the number line is the absolute value of the difference of their coordinates.
If the coordinates of two points on the number line are a and b, then the distance between the two points is
d = |a - b|
The coordinates here are -9 and 7.
distance = |-9 - 7| = |-16| = 16

Answer:
either 2.50$ or 1$
Step-by-step explanation:
i think.........
D
Explanation
Step 1
Let
x represents the smallest number:
as those are three consectutive intergers, the next interger is:
this is the middle number:
middle number=x+1
the next consectutive number is
so, the third number is x+2
Hence,
Step 2
the sum of the smallest number and twice the middle
number is equal to 20 more than the third number?
replacing:
twice the middle=2(x+1)
so, the answer is
D
8^2 + 13^2 = c^2
64 + 169 = c^2
233 = c^2
15.26 = c
your answer would be A. 15.3
hope that helped
