40
12:18 is a 2:3 ratio of pink to blue
If this ratio continues for the population of the box;
the ratio has 5 parts. 100/5 = 20. Each part is 20.
2 * 20 = 40
3* 20 = 60
P:B = 40:60
40 pink chips and 60 blue chips
hope it helps!

Step-by-step explanation:
Answer:
The answer is A
Step-by-step explanation:
10 divided by 5
At first, let us solve The equation
![\sqrt{x+2}\text{ +4 - 4 = 8 - 4}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B2%7D%5Ctext%7B%20%2B4%20-%204%20%3D%208%20-%204%7D)
We will subtract 4 from both sides
![\sqrt{x+2}=4](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B2%7D%3D4)
Then let us square both sides
![x+2=(4)^2\text{ }](https://tex.z-dn.net/?f=x%2B2%3D%284%29%5E2%5Ctext%7B%20%7D)
![x\text{ + 2 = 16}](https://tex.z-dn.net/?f=x%5Ctext%7B%20%2B%202%20%3D%2016%7D)
Subtract 2 from both sides to get the value of x
![x\text{ = 14}](https://tex.z-dn.net/?f=x%5Ctext%7B%20%3D%2014%7D)
You have two choices with 14
Which one will you choose?
To answer this you must know does this value including the domain or not
Let us try this value for x in the equation if the left-hand side equals the right-hand-side then the value is not extraneous
![left-handside\Rightarrow\sqrt{14\text{ + 2}}+4=\sqrt{16}+4=4\text{ +4 =8}](https://tex.z-dn.net/?f=left-handside%5CRightarrow%5Csqrt%7B14%5Ctext%7B%20%2B%202%7D%7D%2B4%3D%5Csqrt%7B16%7D%2B4%3D4%5Ctext%7B%20%2B4%20%3D8%7D)
Since the right-hand side has the same value, so 14 is not extraneous.
So the correct answer is the third choice.
Answer:
Step-by-step explanation:
Domain: the set of all permissible input values. In this particular case, x cannot be -3, because that would cause division by zero. Thus, the domain is (-∞, -3) ∪ (-3,∞)
Range: the range consists of the set of all values of y that are possible. Looking at the parent function, y = 1/x, we see that the range of that function is (-∞, 0) ∪ (0,∞); in other words, y gets close to but never actually reaches zero. This is also true of y = -1 / (x + 3).
Thus, the desired range is (-∞, 0) ∪ (0,∞).
