12. A bird is flying 23 ft above sea level while a dolphin follows the bird from 5 ft below sea level. Which equation shows the correct calculation for the
distance between the bird and the dolphin?

23-5=18

Step-by-step explanation:

ok so 23 feet above would be positive 23 but 5 ft below would be negitive so you write 23-5 and then solve

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.
