Jolie solves a system of equations. is her system solved correctly? why or why not? explain your reasons. y=4x+6 2x+7y=72 jolie's solution: 2x+7(4x+6)=72 2x+7x+42=72 9x+42=72 9x = 30 x= 30/9 y=4(30/9)+6 y=58/3

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
