Zoe is solving the equation 3x – 4 = –10 for x. She used the addition property of equality to isolate the variable term as shown.

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

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.
