If you put 90ml of concentrate in a glass how much water should be added

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.

x+4 would be the answer

there is none

step-by-step explanation:

no negative number is being multiplied by another, so there is not a negative quotient.

edit: you are aware a quotient is division, right?

x = 3

step-by-step explanation:

you haven't given us any choices but we can guess.

-35x = - 105       divide by - 35

-35x/-35 = -105/-35   the minus signs cancel out and 105 can be divided evenly by 35

x = 3
