In the US shoe sizes and foot length are related byt he formula s=3f-24 where s represents the shoe size and f represents the foot in length in inches

Solve this formula for f, foot length in terms of s, shoe size

9 answers

are you just asking for rearrangement?

if so,

(s+24)/3=f
I'm not sure because that's all the question is asking? But from what it looks like, does it just need rearranging? There's another question after that which is : According to this formula if you wear a size 15 shoe how long is your foot
Is the formula they gave wrong
This is not the right formula
yeah just plug in the 15 for s into your formula and rearrange to find f, foot length
13?
13 in is the length of the foot if its a size 15 shoe. that's a big foot
In the formula what is the number 3 and 24 for
they might be products of the proof that derived that formula
