The total number of degrees, D, in an n-sided polygon is given by the formula D=180(n-2). When Janelle solves for n, she gets n=

D+360/180. Sophie solved the same equation for n and got an equivalent equation. Which of the following could be Sophie’s equation?
n=D/180 +2


n=D/180 -2


n=D-178


n=D-182

<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2

Thus, the answer is "A"
Additionally, we can verify this using a square where the total angles add up to 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct

D=180(n-2)
To find n, we start by dividing both sides by 180:
D/180=180(n-2)/180
D/180=n-2
Now, adding 2 to both sides of the equation:
D/180+2=n-2+2
D/180+2=n
So, n=D/180+2

Final answer: First Option n=D/180+2

The standard form of the equation that represents the number of quarters, q, and the number of dimes, d, that austin has in his
AnnZ [9099]
5q + 2d = 270
To determine the intercepts, start by setting d to 0, then to find q. The conditions yield:
5q = 270
q = 54; (0, 54)
2d = 270
d = 135; (135, 0)
This equation illustrates the total number of coins in the piggy bank. For (0, 54), this indicates the quantity of quarters when dimes are absent, while (0, 135) displays the number of dimes when there are no quarters.
