let the first odd number be "x"
formular : (x)+(x+2)+(x+4).
3x+6=57
3x=57-6
3x=51
x=51/3
x=17
apply the formular.
17,(17+2),(17+4)

Answer:
25 %
Step-by-step explanation:
Percentage is given by :
![\%=\dfrac{\text{original value-new value}}{\text{origial value}}\times 100](https://tex.z-dn.net/?f=%5C%25%3D%5Cdfrac%7B%5Ctext%7Boriginal%20value-new%20value%7D%7D%7B%5Ctext%7Borigial%20value%7D%7D%5Ctimes%20100)
Original cost of sweater is $32 and sale cost is $24. So,
![\%=\dfrac{32-24}{32}\times 100\\\\=25\%](https://tex.z-dn.net/?f=%5C%25%3D%5Cdfrac%7B32-24%7D%7B32%7D%5Ctimes%20100%5C%5C%5C%5C%3D25%5C%25)
Hence, 25 % is the markdown on the sweater.
Answer:
8 in.
Step-by-step explanation:
Perimeter of a rectangle, P = 2(L + W)
Value of P = 46.
Length is 7 inches less than the width. This translates to L = W - 7
Substitute L = W - 7 into the perimeter equation, you get
46 = 2(W - 7 + W)
46 = 2(2W - 7)
46 = 4W - 14
4W = 60
W = 60 / 4 = 15 in
L = W - 7 = 15 - 7 = 8 in
