Answer:
Step-by-step explanation:
we know that
The equation of a circle into center radius form is equal to
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
substitute
4 3/16=(4·16+3)/16=67/16=4,1875 (pink ribbon)
5 1/16=(5·16+1)/16=81/16=5,0625 (green ribbon)
4,1875+5,0625=9,25 (total)
9,25·1,60=$14,8
<em>Answer: $14,8</em>
Answer:
x = 3 and y = 7
Step-by-step explanation:
2x + y = 13
<u>+ x - y = -4</u> (adding both equations)
3x - 0y = 9
3x = 9
x = 9/3
x = 3
now substituting
x - y = -4
3 - y = -4
- y = -4 - 3
- y = -7
y = 7 (the negative sign on both sides get canceled)
Therefore,
x = 3 and y = 7
