The ratio of blue marbles to red marbles in a box is 3 to 2. if there are 12 blue marbles in a box then how many red marbles are

valkas [14]

The answer is: 8 red marbles!

This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x

We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8

If this helped, give me brainliest :)

For what value of x is (2x^2+8x)/(x+4)(x^2-9) undefined?

irakobra [83]

Answer:

The value at x =3 is undefined for the given expression

Step-by-step explanation:

Given expression is $\frac{2x^2+8x}{(x+4)(x^2-9)}$

To find for what value of x is undefined in the given expression :

$\frac{2x^2+8x}{(x+4)(x^2-9)}=\frac{2x(x+4)}{(x+4)(x^2-9)}$

$=\frac{2x}{x^2-9}$

$\frac{2x^2+8x}{(x+4)(x^2-9)}=\frac{2x}{x^2-9}$

If we put x=3 in the above expression we get

$\frac{2x}{x^2-9)}=\frac{2(3)}{3^2-9}$

$=\frac{6}{9-9}$

$=\frac{6}{0}$

Therefore $\frac{2x^2+8x}{(x+4)(x^2-9)}=\frac{6}{0}$

The value at x =3 is undefined for the given expression

Pls help asap!! Hhuwdqnjwl

vampirchik [111]

Answer:

14

Step-by-step explanation:

To get the answer, add the whole numbers together and then add the fractions together:

9 + 4 = 13

(You can even stop here because 14 is the closest to 13)

Now, add the fractions:

$\frac{2}{3}+\frac{1}{5}$

To add fractions you have to have a common denominator. To find the common denominator multiply 3 by 5, and 5 by 3. Like this:

$(\frac{5}{5})\frac{2}{3} + \frac{1}{5} (\frac{3}{3} )$

Simplify:

$\frac{10}{15} +\frac{3}{15}$ Distribute everything from above

$\frac{13}{15}$ Add

So, the whole fraction will look like this $13\frac{13}{15}$ . This is closest to 14.

Hope this helps!! Ask questions if you need!
