Answer 3

It seems like you've provided an equation and you're looking for the value of "x". Let's solve it step by step:

$\frac{640}{x + 495} = 250$

To solve for "x", we'll isolate it on one side of the equation. Start by multiplying both sides by $x + 495$:

$640 = 250 \cdot (x + 495)$

Now, distribute 250 on the right side:

$640 = 250x + 250 \cdot 495$

Simplify the right side:

$640 = 250x + 123750$

Subtract 123750 from both sides:

$640 - 123750 = 250x$

Simplify:

$-123110 = 250x$

Finally, divide both sides by 250 to solve for "x":

$x = \frac{-123110}{250}$

$x = -492.44$

So, the value of "x" that satisfies the equation is approximately -492.44.
