Answer:
6394
Step-by-step explanation:
WXYZ
X < Z
Z = ⅔W
W = ⅔Y
Y = 3X
W = ⅔(3X) = 2X
Z = ⅔(2X) = (4/3)X
X has to be a multiple of 3
If X = 3,
Y = 9
Z = 4
W = 6
WXYZ
6394
Answer:12/7
Step-by-step explanation:
7b-4=8
7b-4+4=8+4
7b=12
b=12/7
Let
width,w
length, l = 1.6w ...eqn 1
area, a = l × w ...eqn 2
subst for l in eqn 2
a = 1.6 w × w = 4000
4000 = 1.6 w^2
w^2 = 2500
w = 50
subst for w in eqn 1
l = 50 x 1.6 = 80
length = 80 yds
width = 50 yds
