Answer:
Option A -
is the standard form of the equation.
Step-by-step explanation:
Given : Linear equation - 
To convert into the standard form.
Standard form of the equation is in form Ax+By=C
So to convert this equation into the standard form we have to multiply both side of the equation by -1, so that the value for A is positive.
After multiplying by -1 the form is

is the standard form of the equation.
Therefore, Option A is correct.
As there is no sample expressions which could be the given answer we will solve it by the equation
(amount of time it takes to complete one round)*(number of rounds completed)=
We know that it took Samantha 1.52 minutes to go around once and assume that she continues this pace for 3 rounds. To solve for this we plug in our numbers into our equation.
1.52*3=<span>4.56</span> minutes to complete 3 rounds.
Does that answer your question?
Use this property of logarithms:

Your equation transforms into:

Now, you have to apply the definition of a logarithm to express the equation in exponential form:

In case you don't remember, this is the definition of a logarithm:

The log is the exponent (y) you have to raise the base (b) to in order to get the power (x).
Finally, solve the rational equation:



The correct answer is d.
