First part:

65 cats divided by the ratio of 5 = 13.

13 x ratio of 7 dogs = 91 dogs are at the show.

Second part:

65 cats + 91 dogs = 156 pets are at the show.

Third part: I think the ratio is 7:12. I found the lowest common multiple, which is 13.

91 dogs divided by 13 is 7.

156 pets overall divided by 13 is 12.

Thus, the answer of 7:12.

Hope this helps! Make sure you show your work, for example the addition, multiplication, and division parts of it. :) It shouldn't be too hard, unless you want me to do that as well.

What is z if -1/3+2z=-5/6?

Wittaler [7]

-1/3+2z=-5/6
-2/6+2z=-5/6
Add 2/6 to both sides:
2z=-3/6
2z=-1/2
Divide both sides by 2
z=-1/4

Hope this helps :)

Express f(x) = |x-2| +|x+2| in the non-modulus form. Hence, sketch the graph of f.

alexgriva [62]

Recall that

$|x|=\begin{cases}x&\text{if }x\ge0\\-x&\text{if }x$

There are three cases to consider:

(1) When $x+2$ , we have $|x+2|=-(x+2)$ and $|x-2|=-(x-2)$ , so

$|x-2|+|x+2|=-(x-2)-(x+2)=-2x-4$

(2) When $x+2\ge0$ and $x-2$ , we get $|x+2|=x+2$ and $|x-2|=-(x-2)$ , so

$|x-2|+|x+2|=-(x-2)+(x+2)=4$

(3) When $x-2\ge0$ , we have $|x+2|=x+2$ and $|x-2|=x-2$ , so

$|x-2|+|x+2|=(x-2)+(x+2)=2x$

So

$|x-2|+|x+2|=\begin{cases}-2x-4&\text{if }x$
