Make S the subject of the relation p = s + (sm2)/nr

A.

s = nrpn/r+m2

B.

s = nr + m2 /mrp

C.

s = nrp/mr + m2

D.

s = nrp/nr + m2

Correct Answer: s = nrpn/r+m2

Explanation

p = s + sm2 /nr p = s + ( 1 + m2 nr) p = s (1 + nr+m2/ nr) nr × p = s (nr + m2 ) s = nrp/nr+m2

p = s + sm2 /nr p = s + ( 1 + m2 nr) p = s (1 + nr+m2/ nr) nr × p = s (nr + m2 ) s = nrp/nr+m2
