Question 6 (Multiple Choice Worth 4 points)

Rearrange the equation [tex]$A = xy$[/tex] to solve for [tex]y[/tex].

A. [tex]$y = \frac{x}{A}$[/tex]

B. [tex][tex]$y = \frac{A x}{y}$[/tex][/tex]

C. [tex]$y = \frac{A}{x}$[/tex]

D. [tex]$y = \frac{A y}{x}$[/tex]



Answer :

To solve the equation [tex]\( A = xy \)[/tex] for [tex]\( y \)[/tex], you can follow these steps:

1. Start with the given equation:
[tex]\[ A = xy \][/tex]

2. Isolate y:
To isolate [tex]\( y \)[/tex], you need to get [tex]\( y \)[/tex] on one side of the equation by itself. You can do this by dividing both sides of the equation by [tex]\( x \)[/tex].

3. Perform the division:
[tex]\[ \frac{A}{x} = \frac{xy}{x} \][/tex]

4. Simplify the right-hand side:
On the right-hand side of the equation, the [tex]\( x \)[/tex] terms cancel each other out:
[tex]\[ \frac{A}{x} = y \][/tex]

5. Rewrite the equation:
Now you can rewrite the equation with [tex]\( y \)[/tex] on the left side:
[tex]\[ y = \frac{A}{x} \][/tex]

So, the correct answer is:
[tex]\[ y = \frac{A}{x} \][/tex]

This corresponds to the third option:

[tex]\[ \boxed{y = \frac{A}{x}} \][/tex]
