we have the numbers
we know that
The sum of a number and its additive inverse is 0
so
therefore
the number n is equal to 
the sum is equal to zero
the answer Part a) and Part b) in the attached figure
44 divided by twelve is four so you have to times 2. 1/2 by four so you will have enough so the answer is 10 cups of flour

Answer:
(x-3)^2+(y+2)^2=25
Step-by-step explanation:
c=(a,b) coordinates of center of circle
(x-a)^2+(y-b)^2=r^2 circle equation
a=3 b=-2 r=5
(x-3)+(y+2)=5^2
(x-3)^2+(y+2)^2=25
Let h = the number of half dollars in the jar
and q = the number of quarters
h + q = 30
0.5h + 0.25q = 8.75
multiply the second equation by -2 to get
-h - 0.5q = -17.5
Now add the new equation and the first to eliminate h
h + q = 30
-h - 0.5q = -17.5
----------------------------
0.5q = 12.5
q = 25
There are 25 quarters, so there must be 5 half dollars
