By applying the segment addition postulate, the <u>value of v = 7</u>
- According to the Segment Addition Postulate, it holds that if point C is between points D and E, therefore:
DC + CE = DE
![DC = 2v-15\\\\CE = 3v-8\\\\DE = 27](https://tex.z-dn.net/?f=DC%20%3D%202v-15%5C%5C%5C%5CCE%20%3D%203v-8%5C%5C%5C%5CDE%20%3D%2027)
- Therefore, by substitution, we will have the following equation:
![(2v-15) + (3v-8) = 27](https://tex.z-dn.net/?f=%282v-15%29%20%2B%20%283v-8%29%20%3D%2027)
- Open the bracket and solve for the value of v.
![2v-15 + 3v-8 = 27](https://tex.z-dn.net/?f=2v-15%20%2B%203v-8%20%3D%2027)
![5v - 23 = 27](https://tex.z-dn.net/?f=5v%20-%2023%20%3D%2027)
![5v - 23+ 23 = 27 + 23\\\\5v = 50](https://tex.z-dn.net/?f=5v%20-%2023%2B%2023%20%3D%2027%20%2B%2023%5C%5C%5C%5C5v%20%3D%2050)
v = 10
Therefore, using the segment addition postulate, the <u>value of v = 10</u>

4x + 3 = 11
4x = 11 -3
4x = 8
x =8/4
x =2
answer
the number is 2
Answer:
Step-by-step explanation:
12=3x-2y
2y+12=3x
2y=3x-12
y=(3x-12)/2
y=mx+b
To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be
y=1.5x+b, using point (7,10) we can solve for the y intercept or b
10=1.5(7)+b
10=10.5+b
b=-0.5 so our line is
y=1.5x-0.5
