Answer:
The original price of her purchase was $65.
Step-by-step explanation:
From the information given, you know that $13 represents 20% of the original price and you can use a rule of three to find the value that represents 100%, which would be the original pice of her purchase:
$13 → 20%
x ← 100%
x=(13*100)/20
x=1300/20
x=65
According to this, the answer is that the original price of her purchase was $65.
The answer is D. y=2/3x
If you take the coordinates of each points of the line, (-3, -2) and (3, 2) and use the formula to find the slope, then putting it into formula of a line, you get
Answer:
Both will be at the same page after 6.5 days and the page number will be 180.
Step-by-step explanation:
Let after x days Nora and Lila will be at the same page.
Nora is on page 128 and plans to read 8 pages per day until the next club meeting.
After x days Nora will be at the page number = 128 + 8x
Similarly, Lila is on page 102 and she reads 12 pages per day.
After x days Lila will be on page number = 102 + 12x
Since after x days they will be at the same page
Therefore, 128 + 8x = 102 + 12x
12x - 8x = 128 - 102
4x = 26
x = ![\frac{26}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B26%7D%7B4%7D)
x = 6.5 days
Page number they will be on = 128 + 8(6.5)
= 128 + 52
= 180
Both will be at the same page after 6.5 days and the page number will be 180.
The answer would be 0.95 totaling 1 as there is only 1 chance that this will happen
For this case we have the following expression:
![2x ^ 2 + 2x ^ 3](https://tex.z-dn.net/?f=2x%20%5E%202%20%2B%202x%20%5E%203)
The terms are not similar, so they cannot be added.
<em>Examples of similar terms:</em>
![x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4](https://tex.z-dn.net/?f=x%20%5E%203%20%2B%20x%20%5E%203%20%3D%202x%20%5E%203%5C%5C3x%20%5E%204%20%2B%202x%20%5E%204%20%3D%205x%20%5E%204)
Then, the expression given can only be rewritten as:
![2 (x ^ 2 + x ^ 3)](https://tex.z-dn.net/?f=2%20%28x%20%5E%202%20%2B%20x%20%5E%203%29)
This is taking common factor 2 to both terms.
Answer:
![2 (x ^ 2 + x ^ 3)](https://tex.z-dn.net/?f=2%20%28x%20%5E%202%20%2B%20x%20%5E%203%29)
