-8x + 4 = 36

Subract 4 on both sides 

-8x + 4 - 4 = 36 - 4

-8x = 32

Then divide both sides by -8

-8x/-8 = 32/-8

x = -4

So the answer is D: x = -4

Hope this helps ;P

First one

Angle  DEF = 6x + 37

And twice the angle measure of angle DEF =  measure of arc FGD

So...we have that

2(6x + 37)   =  (19x - 31)    simplify

12x + 74 = 19x - 31     rearrange as

74 + 31 =  7x

105 = 7x      

15 = x

So   DEF = 6(15) + 37 =    90 + 37 =    127°

-8x+4=36

Subtract 4 from each side: -8x=32

Divide each side by -8: x=-4

D: x=-4

I actually had that happen to me as well, they downvoted all of my posts and every question i've asked. I wasn't really bothered by it though seeing as hearts shouldn't really matter. This site is more for asking questions when you need help and getting the help you need or helping others. The hearts are just a bonus. Who cares if you are on the leaderboard or not, that's just my opinion though. I'm sorry that this bothers you and I too wish it would stop happening because it is rude. Although, it really doesn't matter to me because it's not about the amount of hearts you get.

Can guests give or take away points?   I didn't think they could do that......

Sorry if you lost a bunch of points.....

Moderators?

It's as easy as that. Lol 

x=16, thanks :)

Just use the calculator Nickolas....

56000*4 = 224000

Oh yeah you're right! My bad! 

3*4x=12x

3*6=18

12x+18=9x+12

Subtract 18 from both sides: 12x=9x-6

Now subtract 9x from both sides: 3x=-6

Lastly divide both sides by 3 and you get x=-2 so A is the answer 

The second one is easier

We have a cyclic quadrilateral....remember that opposite angles sum to 180“

So 

47 + (7x + 21) = 180    simplify

7x + 68 = 180

Can you take it from here, RP ???

Here is where you went wrong:

close RP    2*(5x+2) = 360 - 87-39       =======>    2*(5x+2) does not equal  5x + 4

                   10x +4  = 234

For the first one...we need to remember something

Angle SUT intercepts diameter ST.....when we have this situation, the measure of SUT = 90°

So   angle TSU  =  180 - 90 - 43 =  47°

And we know that

2 measure of TSU =  9x - 14

2 (47) =   9x - 14

94 = 9x - 14      add 14 to both sides

108 = 9x        divide both sides by   9

12 = x

Oh okay it seems like it could be either one >.< im confused

I think so RP      10x + 4 = 234

                             10x = 230

                                  x = 23

Wait so i'm actually wrong???

Thanks that makes sense lol

close RP    2*(5x+2) = 360 - 87-39

                   10x +4  = 234   continue......

For the second one....note that arc YZ  = 2 * 59 =   118

So we have that

Sum of the measures of the arcs = 360

75 + 118 + (17x - 20) = 360      simplify

55 + 118 + 17x   =  360

173 + 17x = 360       subtract  173 from both sides

17x = 187     divide both sides by 17

x = 11

Thank you! 

Strong work RP !
