Answer:

Step-by-step explanation:
You would start by writing the expression for “subtract 3 from 15", which would be
, then you would add on "then divided by 6", which would make it
Her salary 4 years ago would have been $30,000.
If 45,000 is 15,000 less than double her previous salary, we must first add 15,000 to 45,000 to find what double her salary was.
45,000+15,000=60,000.
Since this is twice her salary, we divide this by 2.
60,000/2= 30,000.
So, her salary 4 years ago would have been $30,000.
I hope this helps!

Answer: Tunnel tent.
Step-by-step explanation:
The tent which has the minimum area requires less nylon to manufacture,
Since, the area of Pup tent = Area of 3 square each having side 8 ft + Area of 2 equilateral triangle having side 8 ft
= 
= 
= 
= 
Now, the area of tunnel tent = Area of square having side 8 ft + total Area of half cylinder having radius 4 ft and height 8 ft
= ![8^2 + \frac{1}{2} [ 2\pi\times 4(4+8)]](https://tex.z-dn.net/?f=8%5E2%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%5B%202%5Cpi%5Ctimes%204%284%2B8%29%5D)
= 
= 
= 
Since, 214.72 < 247.43
Thus, Tunnel tent requires less nylon to manufacture.
