Question

Which is J = rb solved for r?

a. r = j/4b
b. r = 4b/j
c. r = j - 4b
d. r = j/b

I got "a".


Which is M = 300J/P solved for J?

a. J = 300PM
b. J = 300M/P
c. J = 300/PM
d. J = PM/300

I got "d".



So do they both look right? Or not? Plz tell me! I'd like that A LOT! <3

Answer 1

j = r b Divide both sides by b

j / b = r

r = j / b

Answer d


M = 300 J / P Multiply both sides by P

P M = 300 J Divide both sides by 300

P M / 300 = J

J = P M / 300

Answer d
