Answer:
k = 5
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 4, then
20 = 4k ( divide both sides by 4 )
5 = k
W= width
To find dimensions 3x-5 + x + x + 3x-5 = 150
Perimeter = 2l + 2w so that’s why we repeated
So now we simplify
8x - 10 = 150
Add 10 to both sides
160 = 8x
Divide 8 from both sides
X=20
So width is 20 inches. and to find length it is:
3(20)-5 = 60 -5
=55
Length = 55 inches
