Answer:
because when two negatives are together they can't add
Step-by-step explanation:
because when two negatives are together they can't add no matter if there's an addition sign
Given:
Number calories in a 6-inch pizza = 640 calories
For the pizza of 6 inch
![A=\pi(3)^2=9\pi](https://tex.z-dn.net/?f=A%3D%5Cpi%283%29%5E2%3D9%5Cpi)
For the pizza of 12 inch
![A=\pi(6)^2=36\pi](https://tex.z-dn.net/?f=A%3D%5Cpi%286%29%5E2%3D36%5Cpi)
Number calories in a 6-inch pizza = 640 calories, therefore:
![\frac{A_{6\text{ inch}}}{A_{12\text{ inch}}}=\frac{640}{x}](https://tex.z-dn.net/?f=%5Cfrac%7BA_%7B6%5Ctext%7B%20inch%7D%7D%7D%7BA_%7B12%5Ctext%7B%20inch%7D%7D%7D%3D%5Cfrac%7B640%7D%7Bx%7D)
Substitute:
![\begin{gathered} \frac{9\pi}{36\pi}=\frac{640}{x} \\ Simplify \\ \frac{1}{4}=\frac{640}{x} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B9%5Cpi%7D%7B36%5Cpi%7D%3D%5Cfrac%7B640%7D%7Bx%7D%20%5C%5C%20Simplify%20%5C%5C%20%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B640%7D%7Bx%7D%20%5Cend%7Bgathered%7D)
And solve for x:
![\begin{gathered} 1\cdot x=4\cdot640 \\ x=2560 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%201%5Ccdot%20x%3D4%5Ccdot640%20%5C%5C%20x%3D2560%20%5Cend%7Bgathered%7D)
Now, Estimate the number of calories in one slice of a 12 inch pizza:
![\frac{2560}{8}=320](https://tex.z-dn.net/?f=%5Cfrac%7B2560%7D%7B8%7D%3D320)
Answer: 320 calories
When the first number increases by one the second number is added by 4's. So from the first part to the second it added 4 then from the 2nd to the 3rd it skips adding 8 to then just add 12. Then from the 3rd to the 4th it skips adding 16 and adds 20. So the next set of numbers would be (4,64) because it skips adding the 24 and adds the 28.
Hope this helps and is not to confusing :)
Answer:
1 1/3
Step-by-step explanation:
Absolute values are how far away it is from 0, so it is always positive. It is always the positive number of itself, so absolute values of negative numbers are the opposite, and the absolute value of positive numbers and just the same numbers.
