Sum of the faces 1 + 2 + 3......+ 12 = 78
78/12 = 6.5
Given L = 1/5 A
then Adam gives 22
L + 22 = A - 22 sub in the red equation
1/5 A + 22 = A - 22
A = 55 L = 1/5 A = 11 Total = 66 shells
t^2 - 9t - 36 + 7t - 20
t^2 -2t - 56 = 0 Is a bowl shaped parabola ...the minimum value will occur at t = - b/2a = - -2/2 =1
( If needed: use this value fo t in the equation to compute the minimum value of the fxn)
The other 3 out of 5 are right handed 3/5 ths of 50 = 3/5 * 50 = 30 ppl
30 - 20 = 10 ppl more are rt handed then left handed
One large rectangle with sides 9 ( don't count the '3' where the triangles are attached) and 7 = 18 + 14
TWo triangles with legs 8 and hypotenuse 5 = 26 26 + 18 + 14 =
X = (y+1)/(y+2) to get the inverse, switch x's and y 's then solve for x
y = (x+1)/(x+2)
(x+2)y = x+1
xy + 2y -x = 1
x ( y-1) = 1 - 2y
x = (1-2y)/(y-1) is the inverse h-1 (5) = -9/4 = - 2 1/4
1/2 doz + 4 =
1.26 + 4 * .25 = $ 2.26
1 DOZ = $ 2.41 $ 2.41 - 2.26 = 15 CENTS LESS TO BUY 1/2 DOZ + 4 COOKIES
60 yd * .92 /yd - 60 yd * .52/yd = $24 more for the very high priced 3/4 in masking tape (60 yds each)
1/2 bushel + basket + ribbon
23.50 * 1/2 + 8.59 + 2.5 * .88 = total spent = $ 22.54
You're probably young-ish enough to be my granddaughter! THAT's how old I am.... LOL
