Step-by-step explanation:
2x + 1 = 16
2x = 15 (subtract 1 on both sides)
x = 7.5 (divide 2 om both sides)
Since 7.5 is not an integer, (a) is No.
However 7.5 is rational, therefore (b) is Yes.
The answer is A because when you add the angles to get they equal 180. Then just solve for x.
The drawing isn't to scale
Ok so then line p is the equation y=x
is that all you needed?
