Answer:
3 and 8 is a pair of corresponding.
Answer:
6 slices
Step-by-step explanation:
The full pizza is 12 pieces. Divide 12 by 4 to find out how much she ate on Thursday. 1/4 of 12 is 3 so she ate 3 slices on Thursday. Subtract 3 from 12 to find out how much was left for the next day. There were 9 slices the next day. Next, divide 9 by 3 to find out what 1/3 of 9 is. 1/3 of 9 is 3 so subtract 3 from the 9 slices. 6 slices are the original pizza remain.
I used the completing the square method to get the (x+2)^2. The final line is in standard form.
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
Answer:
false
Step-by-step explanation:
as a guy who studied calculus, a lot of things were done that are just mathematically incorrect. for instance,
infinity - infinity is not 0.
0÷0 is undefined. so you cant just equate it to ( 2 × infinity)
to sum up this proof is entirely false.
if you still have any doubts make sure to ask.
