add 2x      and add  1 to both sides of the equation to get

6 < 5x

x> 6/5                      (6/5, + inf)

  23x + 10     -  110    =  5x+8

   solve for 'x'   then   ZJK  =  5x+8

x = x_o  + v_o t  + 1/2 a t²         x = 0 ( the ground level)    x_o = original height of the ball 

                                            v_o = original velocity = 0      a = -10 m/s²          t = 5

0 = x_o - 1/2 (10) (5²)

 x_o = 125 m

(4+6)  is to 6     as    HJ  is to 9

10 / 6 = HJ/9

90 = 6 * HJ

HJ = 15

red    20    40   60  80  100  120   140   160  min

blue  35               70          105      140           min

140 min is  2 hr 20 min   

Assuming 12 pm is noon,  tablets will be taken together at  2:20 PM     or    14:20

x+y=2400                           y = 2400-x

3x + 5y = 9000

Substitute the blue equation into the second eqution , solve for x      then you can solve for y by substituting

   this value of x into one of the equations

....  also ml is a measure of  (liquid) volume

25g / 29.5 ml  =  .8475  g / ml

I THINK:

49 c 5   * 22 =   49! / ( 44! 5!)    * 22 = 41 951 448      so  1 out of 41 951 448

Juanita's saving = 15x       Dan's = 100 + 12x

15 x   >   100 + 12 x   solve for x

3x > 100

x > 33.33 wks        so  at 34 weeks Juanita will have more money than Dan

11 oz/ hr   *   24 hr /day  *  1 gal / 128 oz = ..........gal / day
