Answer:
x=-3 and y= -6
Step-by-step explanation:
we have
6=-4x+y and -5x-y = 21
6+4x=y we substitute y in the second equation
-5x-(6+4x)=21
-9x-6=21
-9x=27
x=-3
we substiture x in the second
-5(-3)-y =21
15-y=21
15-21=y
y=-6

Answer:
64
Step-by-step explanation:
16 x 4 = 64
Let the width be w, then the length is 2w - 2.5.
Perimeter = 2(length + width)
40.6 = 2(2w - 2.5 + w) = 2(3w - 2.5)
3w - 2.5 = 40.6/2 = 20.3
3w = 20.3 + 2.5 = 22.8
w = 22.8/3 = 7.6
Therefore, width is 7.6 cm.
