Step-by-step explanation:

Solution

Interesting question.

The formula for the sum of the interior angles is

(n - 2)*180 = x

In this case, x = 1260

(n - 2)*180 = 1260 Divide both sides by 180

(n -2 )* 180/180 = 1260/180

( n - 2) = 7 Remove the brackets

n - 2 = 7 Add 2 to both sides

n - 2 + 2 = 7 +2 The 2s on the left cancel

n = 9

Step-by-step explanation:

Given;

Sam uses 2/3 cup of sugar to make cookies

Rate = 2/3 cup per batch

To make 5 batches, he would need;

Amount = number of batches × rate per batch

Amount = 5 batches × 2/3 cups per batch

Amount of sugar he would need = 10/3 or 3 1/3 cups
