Answer:

The chances you will get a red marble over a white or blue marble is 30%

Step-by-step explanation:

If you add 5 + 3 + 2 you will get 10

You then turn it into a fraction

3/10 is the chance you will get a red over a blue or white, now we need to convert it into a percentage by turning to 10 into 100 and multiplying 3 x 10

Once you have done that you should have 30/100

Take the 100 away and turn it into a percentage

The answer would be 30%

2x^2+5x+3/x^2-3x-4 divided by 4x^2+2x-6/x^2-8x+16

Masja [62]

Answer: $\frac{x-4}{2x-2}$

Step-by-step explanation:

$\frac{2x^2+5x+3}{x^2-3x-4}$ divided by $\frac{4x^2+2x-6}{x^2-8x+16}$ is the same thing as multiplying $\frac{2x^2+5x+3}{x^2-3x-4}$ by $\frac{x^2-8x+16}{4x^2+2x-6}$ .

The equation we get is:

$\frac{2x^2+5x+3}{x^2-3x-4}*\frac{x^2-8x+16}{4x^2+2x-6}$

With this equation, we can factor each equation:

$\frac{(x+1)(2x+3)}{(x+1)(x-4)} *\frac{(x-4)(x-4)}{2(x-1)(2x+3)}$

We can cancel out like terms since they would be dividing each other:

$\frac{x-4}{2x-2}$
