<span>An equation for the number of donuts y that are left at the end of the day when x donuts are being used during the day is y=24-x. You would subtract x, the number of donuts being used from 24, the total amount of donuts. To get your y.</span>
Answer: 
as a percent is 30%.
Step-by-step explanation:
Divide 3 by 10, which gives you the decimal 0.3.
= 0.3
To convert this to a percent, shift the decimal two places to the right, which gives you 30%.
Perimeter=4h+4
If the base is 2 more than the height, it gives us the equation:
b=h+2
The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.
This can be simplified to be 2h+4+2h or 4h+4
