Answer:
B . R = 5t
Step-by-step explanation:
From the question above; given that R = S + 2t
If s is three times greater than t, it simply means s = 3t
so, we can easily substitute s= 3t in the initial equation.
Replacing or substituting s = 3t in the equation: R = S + 2t, the equation becomes;
R = 3t + 2t
R = 5t
Therefore we could re-write the formula as R = 5t
