Phil has 3 times as many rocks as peter. together, they have 48 rocks. how many more rocks does phil have than peter?

Peter has 12 rocks and Phil has 36 rocks.
Let's say Peter is x.
Phil would be 3x since he has 3 times as many rocks.
3x + x = 48
4x = 48
x = 12
12*3=36

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
