Answer: Option C.
Step-by-step explanation:
The data is:
Destin walked 2km
Jane walked 4000ft.
Let's write both of those in the same units.
The data given is:
1ft = 0.0003048km.
and 4000ft is 4000 times that:
4000ft = 4000*1ft = 4000*0.0003048km = 1.22km
Then if we add those, we get:
Total distance = 2km + 1.22km = 3.22km
So we can already discard option D.
Now, we know that:
1km = 0.6214 miles.
then 3.22 km is 3.22 times that amount:
3.22km = 3.22*1km = 3.22*(0.6214 mi) = 2 miles
The correct option is C.
Hello!
10% off means there's a discount on the jacket, so we will be finding how much the discount is worth and then we'll subtract that from the original cost of the jacket.
Sales tax is basically additional money added to the cost of an item, so we will find what the sales tax is on this and then add that to the cost.
59.27 * 10% = 5.927
59.27 - 5.927 = 53.343
Now, find and add the sales tax.
53.343 * 7% = 3.73401
53.343 + 3.73401 = 57.07701
Round this to 57.1
The total cost of the jacket is $57.1.

![y=-(x^2+5x+6)](https://tex.z-dn.net/?f=y%3D-%28x%5E2%2B5x%2B6%29)
![y=-(x+3)(x+2)](https://tex.z-dn.net/?f=y%3D-%28x%2B3%29%28x%2B2%29)
Set each factors equal to zero.

This would be, as an equation:
</span>
![6x+20=8x-4](https://tex.z-dn.net/?f=6x%2B20%3D8x-4)
Solve:
Add
4 and
-6x to both sides.
![(6x+20)+4+(-6x)=(8x-4)+4+(-6x)](https://tex.z-dn.net/?f=%286x%2B20%29%2B4%2B%28-6x%29%3D%288x-4%29%2B4%2B%28-6x%29)
Simplify.
![24=2x](https://tex.z-dn.net/?f=24%3D2x)
Divide both sides by
2.
![(24)/2=(2x)/2](https://tex.z-dn.net/?f=%2824%29%2F2%3D%282x%29%2F2)
Simplify.
