Hi!

To find the semmetry between the nonagon just do this:

360 / 9 = 40

Ksju [112]

Answer:

i am not sure of these answer but what i know i am gonnna share eith you

Step-by-step explanation:

. The people relied on primitive accounting methods to record the growth of crops and herds. Because there was a natural season to farming and herding, it was easy to count and determine if a surplus had been gained after the crops had been harvested or the young animals weaned.

2. The use of the words "debit" and "credit" in accounting goes back to the days of single-entry bookkeeping, which had as its chief objective keeping track of amounts owed by customers (debtors) and amounts owed to creditors.

3. Accounting as an ad-hoc ordering system devised by the merchant. Its regular use provides the merchant with continued information about business, and allows to evaluate how things are going and to act accordingly.

Multiple 7/9 to the sum of 8 3/7 and 5 11/14

Brums [2.3K]

$\frac{7}{9} \times (8 \frac{3}{7} + 5 \frac{11}{14}) = \\$

$\frac{7}{9} \times (8 \frac{6}{14} + 5 \frac{11}{14} ) = \\$

$\frac{7}{9} \times (13 \frac{6 + 11}{14}) = \\$

$\frac{7}{9} \times (13 \frac{17}{14}) = \\$

$\frac{7}{9} \times (14 \frac{3}{14}) = \\$

$\frac{7}{9} \times ( \frac{14 \times 3 + 3}{14}) = \\$

$\frac{7}{9} \times ( \frac{42 + 3}{14}) = \\$

$\frac{7}{9} \times ( \frac{45}{14}) = \frac{7 \times 45}{9 \times 14} = \frac{5}{2} \\$
