We are given the formula r = st. We evaluate each option to know the correct answer.
A.) S = r/t
r = st
B.) t = r/s
r = st
C.) s = t/r
r = t/s
<span>D.) r = ts
</span>r = st
Therefore, the correct answer among the choice given is option C. It is not equivalent to the formula.

Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-9x - 18 = -9 • (x + 2)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by -9
Remember to flip the inequality sign:
Solve Basic Inequality :
2.2 Subtract 2 from both sides
x > -2
Inequality Plot :
2.3 Inequality plot for
