Answer:
The Answer to the question is 28.8.
Answer:
The item cost 125.53159 cents per ounce if its sales price is $44.28 per kilograms
Step-by-step explanation:
The sale price of item is $44.28 per kilograms. We need it to convert into cents per ounce.
We know that 1 dollar per kilogram = 2.83495 cents per ounce
So, 44.28 dollars per kilograms = 2.83495 * 44.28 cents per ounce
= 125.53159 cents per ounce
So, the item cost 125.53159 cents per ounce if its sales price is $44.28 per kilograms
we have
![(x + 2)^{2}-9=-5](https://tex.z-dn.net/?f=%28x%20%2B%202%29%5E%7B2%7D-9%3D-5)
Adds
both sides
![(x + 2)^{2}-9+9=-5+9](https://tex.z-dn.net/?f=%28x%20%2B%202%29%5E%7B2%7D-9%2B9%3D-5%2B9)
![(x + 2)^{2}=4](https://tex.z-dn.net/?f=%28x%20%2B%202%29%5E%7B2%7D%3D4)
square root both sides
![(x+2)=(+/-)\sqrt{4}\\(x+2)=(+/-)2\\x1=2-2=0 \\x2=-2-2=-4](https://tex.z-dn.net/?f=%28x%2B2%29%3D%28%2B%2F-%29%5Csqrt%7B4%7D%5C%5C%28x%2B2%29%3D%28%2B%2F-%292%5C%5Cx1%3D2-2%3D0%20%5C%5Cx2%3D-2-2%3D-4)
therefore
<u>the answer is</u>
the resulting equation is ![(x+2)=(+/-)2](https://tex.z-dn.net/?f=%28x%2B2%29%3D%28%2B%2F-%292)
A ratio equivalent to 3:11 will be multiplying each term by a common term. Eg 3 x 2 : 11 x 2 = 6:22
