? Given that
40 : 3 = 6 : 5
Calculate the value of x.

x = 0.9

Step-by-step explanation:

according to proportion;

= 4x : 3 = 6 : 5

= 4x / 3 = 6 / 5

= 4x = (6 / 5) × 3

= 4x = 1.2 × 3

= x = 3.6 / 4

= x = 0.9 or 9/10

sure i'm up for it

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.
