Suppose S is between R and T. Use the Segment Addition Postulate to solve for y.
RS=7y−1
ST=y+5

RT=28
y=

Respuesta :

Answer:

3

Step-by-step explanation:

S is a point on line segment RT.

So RS+ST=RT.

(7y-1)+(y+5)=28

Combine like terms:

8y+4=28

Subtract 4 on both sides:

8y=24

Divide both sides by 8:

y=3
