Answer:
Janet has coins worth 252.5, 101, and 50.5.
Step-by-step explanation:
Let us call the three coins
, and
.
The first coin
is 5 times another coin<em> (let's say </em>
); therefore,
,
and the third coin is 2 times the value of another coin<em> (it's coin </em>
<em>):</em>
<em />
<em>.</em>
The total worth of all coins is 404; therefore,
![a+b+c =404](https://tex.z-dn.net/?f=a%2Bb%2Bc%20%3D404)
or
![5b+b+2b =404](https://tex.z-dn.net/?f=5b%2Bb%2B2b%20%3D404)
![8b =404](https://tex.z-dn.net/?f=8b%20%3D404)
![\boxed{b = 50.5}](https://tex.z-dn.net/?f=%5Cboxed%7Bb%20%3D%2050.5%7D)
with the value of
in hand, we find
and
:
![a = 5b = 5(50.5)](https://tex.z-dn.net/?f=a%20%3D%205b%20%3D%205%2850.5%29)
![\boxed{a = 252.5}](https://tex.z-dn.net/?f=%5Cboxed%7Ba%20%3D%20252.5%7D)
and for ![c:](https://tex.z-dn.net/?f=c%3A)
![c = 2 b = 2 (50.5)](https://tex.z-dn.net/?f=c%20%3D%202%20b%20%3D%202%20%2850.5%29)
![\boxed{c = 101}](https://tex.z-dn.net/?f=%5Cboxed%7Bc%20%3D%20101%7D)
Thus, Janet has 3 coins worth 252.5, 101, and 50.5.
3 - 14 = -11
Because you do 14 - 3 which equals eleven and then you add the negative sign

Answer:
(x +4)^2 + (y-2)^2 = 16
Step-by-step explanation:
We can write the equation for a circle with the formula
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
We know the center is at (-4,2) and the radius is 4
(x- -4)^2 + (y-2)^2 = 4^2
(x +4)^2 + (y-2)^2 = 16
I think the answer would have to be D. If the diameter, which is the distance from one point on the circle through the center to another point on the circle, is halved then the amount of concrete that will be needed will be multiplied by 4. I think that's right I am so sorry in advance if that was incorrect. Have a beautiful rest of your day. Stay safe. C O V I D - 1 9 IS REAL THIS COULD MEAN YOUR LIFE!!!
