Answer:

−6634

Step-by-step explanation:

((5)(−3))2−((2)(5)−(3)(−3))3

=(−15)2−((2)(5)−(3)(−3))3

=225−((2)(5)−(3)(−3))3

=225−(10−(3)(−3))3

=225−(10−(−9))3

=225−193

=225−6859

=−6634

Answer:

The time it took until 2 inches of rain fell is 8 hours

Step-by-step explanation:

You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x

To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:

2= 0.25*x

Solving:

$\frac{2}{0.25}=x$

8 = x

So, remembering that the amount of time it had been raining, x, is expressed in hours, <u><em>the time it took until 2 inches of rain fell is 8 hours</em></u>.

In order to find the equivalent expression, let's use the following property:

$a-(-b)=a+b$

In other words, when subtracting a negative number, we can just add the corresponding positive number, that is, switch the two negative signs for a positive sign.

So we have that:
