Sally needs 2/3 of a pound of potatoes. This is 1/3 of a pound more than 4/3 of the potatoes Sally has in her pantry
amid [387]

Lets assume, Sally has X pound of potatoes in her pantry.

So, 4/3 of the potatoes Sally has in her pantry = \frac{4}{3}X

Now, Sally needs 2/3 pound of potatoes and this 2/3 pound of potatoes is 1/3 pound more than that \frac{4}{3}X

So the representing equation will be:

\frac{2}{3} =  \frac{1}{3}+ \frac{4}{3}X

\frac{2}{3} - \frac{1}{3} = \frac{4}{3} X (subtracting \frac{1}{3} from both sides)

\frac{1}{3}= \frac{4}{3}X

1= 4X (multiplying both sides by 3)

X =\frac{1}{4}

So, Sally has \frac{1}{4} pound of potatoes in her pantry.

A circle is centered at the point (5,-4) and passes through (-3,2). The equation of this circle is (x+___)²+(y+___)²=____.
JulsSmile [24]
The equation of a circle is:
 (x-h)^2 + (y-k)^2 = r^2
 where (h,k) is the location of the center and r is the radius.  So we need to find h, k, and r.  The center is given as (5,-4) so h = 5 and k = -4:
 (x-5)^2 + (y-(-4))^2 = r^2
 (x-5)^2 + (y+4)^2 = r^2
 So we need to find r.  Use the distance formula to find the distance between (5,-4) and (-3,2):
 r = [(5-(-3))^2+((-4)-2)^2]^1/2
 r = [8^2 + (-6)^2]^1/2
 r = [64 + 36]^1/2
 r = 100^1/2
 r= 10
 The final equation is:
 (x-5)^2 + (y+4)^2 = 10^2
