Question

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

A. R = 3(s + t)
B. R = 5t
C. R = 3(s + 2t)
D. R = 5s

Answer 1

Step-by-step explanation: R=3 + 2t

R=5t

Answer 2

B . R = 5t

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
