Y=kx
k=constant of variation
given
k=12
y=36
36=12*x
divide both sides by 12
3=x
x=3
Answer:
Length = 4 inches
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
If x = 2
Perimeter = 8x - 4
= 8(2) - 4
= 16 - 4
= 12 inches
Width = 3x - 4
= 3(2) - 4
= 6 - 4
= 2 inches
Perimeter of a rectangle = 2(length + width)
12 = 2(length + 2)
12 = 2length + 4
12 - 4 = 2 length
8 = 2 length
Length = 8/2
Length = 4 inches
Answer:
Step-by-step explanation:
so 20% of the total price equals $ 30
let x represent the total price
turn ur percent to a decimal
0.20x = 30
x = 30 / 0.20
x = 150 <=== total price
