Answer:
put x=1/2, you will get, r(1/2)=20*1/2-89
=10-89= -70.
hope it will help.

Answer:
- 35 1/3°
- 54 2/3°
Step-by-step explanation:
Angle AOB and BOC create a complementary angle. This means when two angles sum up to 90°. We can write an equation for this problem;
(x + 8) + 2x = 90
~Remove parenthesis
x + 8 + 2x = 90
~Combine like terms
3x + 8 = 90
~Subtract 8 to both sides
3x = 82
~Divide 3 to both sides
x = 82/3 or x = 27 1/3
Use what have for x to solve for the angle measures.
Angle AOB:
x + 8
(27 1/3) + 8
35 1/3°
Angle BOC:
2x
2(27 1/3)
54 2/3°
Check.
35 1/3 + 54 2/3 = 90°
Best of Luck!
Answer: x>2/9
Step-by-step explanation:
2/3<3x
3x>2/3
x>2/9
1/2 hour. 30/60 = 1/2 3 divided by 6 is 1/2 since it's not possible for it to be 1
