Answer:
(d-5)
Step-by-step explanation:
we know that
The phrase"five fewer than d days" is equal to subtract 5 from the number d
so
d minus 5-----> (d-5)
You use $25 each week for food from the grocery store how many weeks if you have 145,775
A+b = c+d
a+b = 770/2 ( a+b+c+d = 770)
a+b = 385
c+d = 385
a+b+a-b = 385+49
2a = 434
a = 434/2
a = 217
a-b=49
217-49= b
b = 168
c+d+c-d = 385+211
2c = 596
c = 596/2
c = 298
c-d = 211
c-211= d
298-211 = d
d = 87
Therefore, a=217, b=168, c=298, d=87

Answer:
radius 4
center (3,6)
Step-by-step explanation:
(x - h)^2 + (y - k)^2 = r^2
coordinates of the center (h, k) and the radius is (r)
x² + y²- 6x - 12y +29=0
x² - 6x + y²- 12y +29=0
(x² - 6x) + (y²- 12y) +29=0
complete the square
(x² - 6x) + 9 + (y²- 12y) +36 +29= + 9 +36
(x² - 6x + 9) + (y²- 12y + 36) = + 9 +36 -29
(x-3)^2 + (y-6)^2 = 16
(x - h)^2 + (y - k)^2 = r^2
coordinates of the center (h, k) and the radius is (r)
center (3,6)
radius 4
