We can use a factorial to solve this:
3! = 3 * 2 * 1 = 6
So, she can wear them in a total of 6 combos.

Answer:
zero
Step-by-step explanation:
Dividing the second equation by -3, it becomes ...
x -3y = 7/3
Compared to the first equation, ...
x -3y = 5
we see that it is <em>inconsistent</em>. No values of the variables can satisfy both equations. There are no solutions.
2,500 kiloliters = 2,500 × 10 = 25,000 hectoliters
<span>25,000 − 24,500 = </span>500<span> hectoliters</span>
<span>450
Camila started with 450 cards. She gave Erin half of them (225) and her brother a sixth of them (75). She was left with 150 cards (450 - 225 - 75 = 150).
If x = number of cards Camila started with, then x/2 = half the cards and x/6 = one sixth of the cards. 150 = number of cards left.
This can be represented as:
x - x/2 - x/6 = 150
Multiply by 6 and solve for x
6x - 3x -x = 900
2x = 900
x = 450 = number of cards Camila started with</span>
Answer:
The correct answer is Option 3: 12y
Step-by-step explanation:
A polynomial term is usually made of a variable and a co-efficient.
Like terms are those terms that have the same variables i.e. x and 44x are like terms.
Given expression is:
All the terms have only y which means that all three terms are alike.
The coefficients of like terms are added or subtracted according to their sign.
= 12y
Hence,
The correct answer is Option 3: 12y
