Answer:
9.1) k = 4.6
9.2) k = 6
Step-by-step explanation:
9.1) [tex] 115 = k(25) [/tex]
To find constant of proportionality, k, divide both sides by 25
[tex] \frac{115}{25} = \frac{k(25)}{25} [/tex]
[tex] 4.6 = k [/tex]
Constant of proportionality, k = 4.6
9.2) [tex] 15 = k(2.5) [/tex]
To find constant of proportionality, k, divide both sides by 2.5
[tex] \frac{15}{2.5} = \frac{k(2.5)}{2.5} [/tex]
[tex] 6 = k [/tex]
Constant of proportionality, k = 6
