Answer:
Answer: d is 20
Step-by-step explanation:
[tex]{ \rm{p \: \alpha \: d}} \\ \\ { \rm{p = kd}}[/tex]
k is a constant of proportionality
• When p = 3, d = 5.
[tex]{ \rm{3 = (k \times 5)}} \\ \\ { \rm{k = \frac{3}{5} }}[/tex]
• Therefore, equation becomes;
[tex]{ \rm{p = \frac{3}{5} d}}[/tex]
• Let's find d when p is 12;
[tex]{ \rm{12 = \frac{3}{5}d }} \\ \\ { \rm{d = \frac{12 \times 5}{3} }} \\ \\ { \underline{ \underline{ \rm{ \: \: d = 20 \: \: }}}}[/tex]
