A) P= d/m RT; M

P= d/m RT|x m
P x m = dRT|:P
m = dRT/P

b) f= 9/3c + 32; c
f= 9/3c + 32 | x 3c
f x 3c = 41 |:3f
c = 41/3f

c) s= vt + at²/2; a
s= vt + at²/2 \ x 2
2s = vt + at² | - vt
2 s - vt = at² |: t²
2 s - vt /t² = a

d) F=G Mm/r²; m
F=G Mm/r² | x r²
F x r² = GMm |:GM
F x r²/ GM = m

A) m=d/PRT
b) c=⅓(f-32)
c) a=2(s-vt)/t²
d) m=Fr²/GM
