For this case, the first thing we must do is define variables.
We have then:
x: initial amount of cards
We now write the equation that models the problem:
![x - (\frac{1}{2}) x - (\frac{1}{4}) x = 75](https://tex.z-dn.net/?f=%20x%20-%20%28%5Cfrac%7B1%7D%7B2%7D%29%20x%20-%20%28%5Cfrac%7B1%7D%7B4%7D%29%20x%20%3D%2075%20%20%20%20)
![(\frac{1}{4}) x = 75\\x = 75 * 4\\x = 300](https://tex.z-dn.net/?f=%20%28%5Cfrac%7B1%7D%7B4%7D%29%20x%20%3D%2075%5C%5Cx%20%3D%2075%20%2A%204%5C%5Cx%20%3D%20300%20%20%20)
Therefore, the initial amount of cards is 300
Answer:
Latoya had 300 cards at the beginning
Dilation and reflection
-multiplication of - =reflection
example -(x)
-multiplication of any number other than 1=dilation
example 3x
-addition/subtraction inside the function=horizontal translation
Example (x-3)
-addition/subtraction outside the function=vertical translation
Example x-3
Answer:
x=7-13
Step-by-step explanation:
Answer:
The price at discounted rate = $ 16.8
Step-by-step explanation:
Given in question as ,
The rate of cashews for selling = $14 per pound
Now Carla discounting the price by 20%
So , new price of cashews = 14 - (20% × 14)
Or, = 14 ×![\frac{80}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B100%7D)
Or, New price of cashews = $11.2 per pound
Again , Carla buys
pounds of cashews at discounted price
∵ , cost of 1 pound cashews = $ 11.2
∴ , cost of
pound =
× $ 11.2
= ![\frac{3×11.2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%C3%9711.2%7D%7B2%7D)
= $ 16.8
Hence the price at discounted rate = $ 16.8 Answer
