Answer:
Step-by-step explanation:
6. Yes: these two angles are opposite 2 equal line.
7. No: We don't know that AC bisects <JAD
8. No: We don't know that JCA or DCA are right angles.
9. Yes. Both angles have AC in common. JD is a straight line which has 180 degrees. AC intersects a JD and creates 2 angles. We know their total but not their equality.
10. Yes. They are given as equal.
Not everything you see is true just because it looks that way.

Answer:
x < 4
Step-by-step explanation:
3/4(x+8)>1/2(2x+10) (multiply both sides by 4)
(4)(3/4)(x+8)>(4)(1/2)(2x+10)
3(x+8)>2 (2x+10) (expand parentheses by distribution property)
x(3)+8(3)>(2x)(2)+10(2)
3x+24>4x+20 (subtract 3x from both sides)
3x+24 - 3x > 4x+20- 3x
24 > x+20 (subtract 20 from both sides)
24 - 20 > x + 20 - 20
4 > x (rearrange)
x < 4
The answer is 11 if you use PEMDAS! Here is my work:
9+4-4+2 = I multiplied and divided first
13-4+2....9+2....11
Hope this helped :))
