Answer:

x = 33.3

Step-by-step explanation:

(n-2)*180

(6-2)*180 = 720

3x+6x+4x+7x = 20x

6+41-51-11+62+7 = 54

20x+54 = 720

20x = 666

x = 666/20

x = 33.3

Help please! Could you explain it too?
Olegator [25]

Answer:

a. Not proportional

b. Proportional;

k = ⅞

Step-by-step explanation:

A proportional relationship is usually represented in the format, y = kx. k here represents constant of proportionality. This shows that x and y are directly proportional.

a. y = -2x + 9 is not a proportional equation.

b. y = ⅞x is a proportional equation.

Constant of proportionality: k = ⅞
