5/9 to chose odd card, 3/6 to roll even number
To find the length, divide the peremiter by 2 and then subtract the width.
Length= Peremiter/2 - width
L = P/2 - W
L = 168/2 - 36
L = 84 - 36
L = 48
The length is 48
Answer:
3x+0.3=3.3.
\ /
We move all terms to the left:
3x+0.3-(3.3.)=0
We add all the numbers together, and all the variables
3x+0.3-0=0
We add all the numbers together, and all the variables
3x+0.3=0
We move all terms containing x to the left, all other terms to the right
3x=-0.3
x=-0.3/3
x=-0.3/3

Cramer's rule works as follows:
x+3y=16
3x+y=8
Then
x=Dx/D
y=Dy/D
where Dx,Dy,D are 2x2 matrices formed from of coefficients and right hand side.
D=
1 3
3 1
=1-9=-8
Dx=matrix D with first column replaced by the vector [16,8]=
16,3
8 1
=16-24
=-8
Dy=matrix D with second column replaced by the vector [16,8]=
1 16
3 8
=8-48
=-40
Therefore
x=-8/-8=1
y=--40/-8=5
Check:
x+3y=1+3(5)=16
3x+y=3(1)+5=8 ok.
