Question

D = 360 - 180/N N = 9

Answer 1

Answer:

D = 340

Step-by-step explanation:

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

$d = 360 - \frac{180}{n} \\ d = 360 - \frac{180}{9}$

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.

$d = 360 - \frac{180}{9} \\ d = 360 - 20$

Finally, we'll subtract 20 from 360.

$d = 360 - 20 \\ d = 340$
