Question 253916: I have been given this formula. R=s+2t If I know that s is three times greater than t, how coul I rewrite this formula?
R=3(s+t)
R=5s
R=5t
I don't know which one would be the best. Please help. Thank you. Leanne

You can put this solution on YOUR website!
"I know that s is three times greater than t" ___ s = 3t

substituting the equivalent value for s ___ R = 3t + 2t ___ R = 5t
