a = adult tix                         value =  $ 7a

c = children = (272-a)         value =  $ 4 ( 272-a)                 summed , they equal 1694

7a             +         4 (272-a)               = 1694               

     solve for a     then    c = 272-a            

 Supplementary means they add to 180 ^o

a        +           3a-184         = 180          solve for a      then the other is   3a-184

The possible values of x are 7 and - 7.

Factors of 28   1  2  4  7   14   28

Factors of 21   1 3  7  21

   The greates common factor of 21 and 28 is 7

L/M = ?    M/N = ?        they are not in your question....

Can someone please help? :(

62.      IF the line BD is passing through the center of a circle, then the angle x must be 90 degrees!

           IF lines BC and CD are congruent, then the value of angle x is 66 degrees

(btw, those suggested answers are there to be ignored)

Thanks Ginger!

Well just learn more spelling and words do some over your grade like what I do

L & R faces             8 x 14     x 2

F and B faces         8 x 8       x2

Top  and bottom   (  2 x 14  +  6 x 4) x 2         Add them all together

1/       5x + 3 = 7x -1

          -2x = -4 

           -x = -2 | *-1

           x = 2

2/       5x +2(x + 7) = 14x - 7

          5x + 2x +14 = 14x - 7

          -7x = -21

          -x = -3 | *-1

           x = 3

3/        12t - 10 = 14t + 2

            -2t = 12

             t = -6

4/          5(z + 1) = 3(z + 2) + 11

             5z + 5 = 3z + 6 + 11

             2z = 12

              z = 6

2x+5y=8      arrange into y = mx+b fomr to find slope,m

y=-2/5x+8/5     slope = -2/5

-3ax+4y=-6

y= 3/4a x -6/4        3/4a = -2/5      solve for a

A     l x w = 96

       (2w - 4) x w = 96      solve for w   

B    1 x    + 5(19-x) = 55       solve for x = number of $1 bills    then $5 bills = 19-x

Mr. BB, the Moron of Math is now offering (condescending) editing advice. … Christ! We are bloody doomed: within a generation we will not no what won plus won equals nor will we no how to right about it. ...  

...Most spelling-checkers will typically not flag wrong words when the spelling is correct. There are spell checkers that detect homonym and similar word errors, but, except for the very advanced applications, they often just flag them regardless of context.

Ilorty, here are three (3) posts where you used “aloud” for “allowed”  

Draw a cartesian coordinate system of the given points

A  -30, 18    and  B   -10,-27       find 1/5th of the way from A to B

x  from -30 to -10 is a change of 20    1/5 *20 added to -30 = -26

y  from 18 to -27 is a change of -45    1/5 * -45 added to 18 =  9   

-26, 9    is 26 miles west of port and 9 miles north of port

Oh, you are right! I just made a silly mistake...

Let angle P be x and angle Q be y:

2y-3=x

x+y=180

x=180-y

So, substitute into the first equation:

2y-3=180-y.

Use a little algebra:

2y-3=180-y

2y+y-3=180-y+y

3y-3=180

3y-3+3=180+3

3y=183

(3y/3)=(183/3)

y=183/3=61

As a matter of fact, the question I posted came from a friend, and I would politely urge you to not jump to such conclusions. 

And yes, the question does reveal too much personal info, so I have flagged it.

ilorty, I'm not the original poster, but I need clarification 

       how do you get from     5x + 2(x + 7) = 14x – 7  

                                 to     5x + 10x + 14 = 14x -7   

I was thinking it should be    5x + 2x + 14 = 14x – 7   

Please help.
