e + 4e = 270

e = 54   then   p = 216        to have equal cards they would each have 135 (because total is 270)  so  e  needs to get  81 cards from p

y = 3/4 x + b         where 'b' is the y-axis intercept.

2000 x 12 % =

  2000 x .12 = .................

This equation is for converting F^o  to/from  C^o

12=5/9(f-32)        Multiply both sides of the equation by  9/5 to get:

21.6 = f-32           Now add 32 to both sides

53.6  = f

3 x 5 x 9   is   135 cubes       total surface area    6 x 135 = 810 cm²

original painted area =   2 x    3x5      +    2 x    5 x 9     +    2 x    9 x 3    cm²

 you should be able to finish.......

First you need to graph the points....

   then, I would calculate the entire rectangular area..... then subtract the two areas of the red right triangles for a final result:

98.5 pi    units²

Since we are only looking for the x coordiantes, equate the two parabolas

-x^2 -x + 1 = 2x^2 - 3x

3x^2 -2x - 1 = 0                Quadratic Formula shows  c and a   are   1   and   -1/3      <====== you can finish

How many donuts did Mrs. Pound have to start?

Choose a red one  2 out of 9    2/9

  now there are 8 marbles left

      choose a blue   3/8

     now there are 7 left

         choose a green    4/7

2/9  *  3/8  *   4/7   = ...................
