x=-11
we know that
Points A,B,C,and D are collinear and positioned in that order
so
AD=AB+BC+CD -----> by addition segment postulate
we have
AB=2x+30
AD=x=32
substitute the given values and solve for x
x+32 = (2x+43)
Group terms that contain the same variable
2x-x=32-43
x=-11
Answer:
you didnt put a pic bro how can we answer
Answer:
x=20
Step-by-step explanation:
3x-10=x+30
2x-10=30
2x=40
x=20
Answer:
x > 4
Step-by-step explanation:
-3x -24 < -36
Add 24 to each side
-3x -24+24 < -36+24
-3x< -12
Divide each side by -3, remembering to flip the inequality
-3x/-3 >-12/-3
x > 4
