Answer:
D
Step-by-step explanation:
For the segment addition postulate, two segments added together have to equal the third segment. In other words, if we added them together, the sum should be the first letter of the first line and the second letter of the second line.
BC + CD = BD
y=2/5x+3/5
Use the slope formula to get the slope:
m=4/10
m=2/5
The y intercept is 3/5
The equation is y=2/5x+3/5
p = 80 and q = 40
so p - q = 80 - 40 = 40
x=26.8
