Question

Suppose you're given the formula R=s+2t. If you know that s is three times greater then t, how could you re-write the formula?

A. R=3(s+2t)

B. R=3(s+t)

C. R=5s

D. R=5t

Answer 1

D. because R = s+2t => R = 3t + 2t => R = 5t

Answer 2

D. R=3t + 2t=5t

Answer 3

r = s + 2t

given that s = 3t

hence, r = 3t + 2t

r = 5t is the right answer

Answer 4

Answer D

Reason S=3T

3T+2T =5T  

Answer 5

k so first u want to get just R alone so its

R=s+2t and u want to take out 2 so 2/2t so now u got R=s+t

and know if u know s is 3* greater then t its 5  then u got R=5+2t then u got ur answer R=5+2t so the answer is C.
