Which is equivalent to 3x/x+5 - x-5/x
which is equivalent to 3x/x+5 - x-5/x - 1

Answers

Answer 1
Answer:

Answer:

B. (2x^2+25)/(x(x+5))

Step-by-step explanation:

x((3x)/(x+5))-(x+5)((x-5)/(x))

= (3x^2)/(x(x+5)) - ((x-5)(x+5))/(x(x+5)) = (3x^2-(x-5)(x+5))/(x(x+5))

= (3x^2-(x^2-25))/(x(x+5))

= (2x^2+25)/(x(x+5))

you have the number 6 add 14 more

How Can you divide that

Answers

First you ask yourself, can 8 go into 1?  The answer is no.  Can 8 go into 12? Yes, 1 time.  So you put 1 on top of the 2 and subtract 8 from 12.  That gives you 4.  Then you pull down the 8 from 128 and ask how many times can 8 go into 48?  The answer is 6.  So your answer is 16.  Hope I helped!
You can divide 128 by 8 and it would equal 16

15 is 75% of what?

Answers

Answer: 20

Step-by-step explanation: In this problem, 15 is being represent as the part so we will have 15 over the part which we don't know which is going to be represented as 'x.' 75% is obviously the part which we will put over 100%.

Now, we can apply the cross products.

1500% = 75%x

X = 20
20 because 75% of 20 is 15
