Answer:

15(x - 5)(x - 3)²

Step-by-step explanation:

factor both denominators and see what you need to do to make them equal...

(x² - y²)/[(x - 5)(x - 3)]           y²/[15(x - 3)(x - 3)]

the first denominator has (x - 5)(x - 3)          

the second denominator has 15(x - 3)(x - 3),

the least common denominator between them would be

15(x - 5)(x -3)(x - 3)     or  15(x - 5)(x - 3)²

Answer:

(3x+5y)/8

Step-by-step explanation:

The total amount is 150+250=400

We then do (3x+5y)/2 × 1/400

This equals (3x+5y)/800

We multiply that  by 100 giving us the final answer.

Two towns accumulated different amounts of snow. In town 1, the snow depth is increasing by 3 1/2 inches every hour. In town 2 t
san4es73 [151]

Let umber of hours in which snowfalls of the both towns become  equal = x

Given that rate at which snow depth is increasing in town 1 =

3\ \frac{1}{2}=\frac{2*3+1}{2}=\frac{6+1}{2}=\frac{7}{2} inches per hour

Then amount of snow fall in x hours in twon 1 = \frac{7}{2}x


Given that rate at which snow depth is increasing in town 2 =

2\ \frac{1}{4}=\frac{2*4+1}{4}=\frac{8+1}{4}=\frac{9}{4} inches per hour


Then amount of snow fall in x hours in twon 2 = \frac{9}{4}x


when snow fall becomes equal then we get equation:


\frac{9}{4}x = \frac{7}{2}x

\frac{9}{4}x = \frac{14}{4}x

0 = \frac{14}{4}x-\frac{9}{4}x

0 = \frac{5}{4}x

0*\frac{4}{5}=x

0=x

Hence final answer is 0 hours.
