x^2 -x = x (x-1) that's about it
(7 *77 + 5 * x )/ (5+7) = 82
x= 89 scores needed on next 5 exams
7/8 of the recipe is water 7/8 x 1gal = 7/8 gallon of water needed
4 quarts X 7/8 = 28/8 quarts of water = 3 1/2 q
LCM of 4 6 and 10 is 60 so every 60th crab pot has 3 balloons 600/60 = 10
Slope = rise/run = y2-y1 / x2-x1
-7-2 / 13 - -2
-9 / 15 = -3/5
x-y = 36
x = 2y +4
sub into the first equation
2y+4 - y = 36
y = 32
then x = 2y+4 = 68
The students are partitioned into 1:7 + 1+7 = 8 parts 1/8 are left and 7/8 are right handed
7/8 x 32 == 28 right handed
45% x 2003 = .45 x 2003 = 901.35
15% * n = 901.35
n = 901.35/.15 = 6009
Those are x and y coordinates on the unit circle.....they are both negative , so it is in quadrant 3
sin = - 1/2
cos = - sqr3/2
7 pi /6 is 210 degrees
40 % white 20% blue 40% red
Red and white amounts are equal....and each is twice as much as blue (40% vs 20%)
4 cups of blue means 8 cups of white and 8 cups of red total = 20 cups lilac
