Question

D = 360 - 180/N N = 9

Answer 1

D = 340

Explanation:

First, we input the value 9 in place of the variable N.

`d = 360 - (180)/(n) \\ d = 360 - (180)/(9)`

Next, we begin to perform the order of operations to solve the equation. The Order of Operations (or PEMDAS) dictates that, from left to right, we should start from:

Parentheses

Exponents

Multiplying and Dividing

Adding and Subtracting

So first, we'll divide 180 by 9.

`d = 360 - (180)/(9) \\ d = 360 - 20`

Finally, we'll subtract 20 from 360.

`d = 360 - 20 \\ d = 340`

Answer 2

D=340

Explanation:

D=360 - 180/9

=360 - 20

=340
