You find greatest common factor for both the numerator part and the denominator part.

First look at numerator
5x^2 10xy

What is the greatest common factor?

5 and x

So
5x (x + 2y)

[you can multiply them back and see that you get the initial equation. Also, cant simplify x+2y any further so this is correct]

Now the denominator:
X^2 +2xy

Again, find GCF.
It is only x

So,

X(x+2y)

Now what do we have?

5x(x+2y)/ x(x+2y)

You can see that x+2y is present both in numerator snd in denaminator, so you can cancel them out.
You are left with.

5x/x

You can cancel x’s too and you are left with

schepotkina [342]

Answer:

C 1/2

           = 1/2

Dan has the same number of nickels and dimes in his piggy bank. If the total amount of those coins is $0.90, how many of each co
SpyIntel [72]

Answer:

6.

Step-by-step explanation:

We can start by defining a couple things.

x = amount of nickels

y = amount of dimes

Since he has the same amount of each, we can say this.

x = y

And because we know it totals 0.90, we can say this.

0.05x + 0.10y = 0.90

then, we substitute and get this.

0.05x + 0.10x = 0.90

Simplify.

0.15x = 0.90

Divide both sides by 0.15.

x = 6

So we have 6 nickels, and they both are the same, so we have 6 dimes.
