remember that when multiplying indices, you add the powers. When dividing indices, remember that you subtract the powers. When taking the power of a number which has already been raised to a power, you must multiply the values of these powers. Any value raised to the power of 0 is equal to 1.

What is n-9 divided by 10=-2

DerKrebs [107]

The value of n is 11.

<u>Step-by-step explanation</u>:

The given expression is (n-9) ÷ 10 = -2

<u>To find the value of n</u> :

From the expression, it is determined that (n-9) is the numerator and 10 is the denominator.
Cross multiply the denominator in the left side of the expression to the another side.

The expression becomes (n-9) = (10 $\times$ -2).

⇒ n-9 = -20

Keep the n term on one side and the constants on other side.

⇒ n = -20+9

⇒ n = -11

Therefore, the value of n is 11.

Einstein Office Equipment has a rental plan for office machines. A fax machine that lists for $722.98 can be rented for 22% of t

Archy [21]

Answer:

$13.68

Step-by-step explanation:

Assuming they rent for 1 year, the cost is broken down as follows:

Annual renting cost = 22% of 722.98 = $\frac{22}{100}*722.98=0.22*722.98=159.06$

Usage charge = 3.2% of 159.06 = $\frac{3.2}{100}*159.06=0.032*159.06=5.09$

Thus,

Total annual charge = Annual renting cost + Usage charge = 159.06 + 5.09 =164.15

Monthly rental charge would be 164.15 divided by 12 (12 months in 1 year):

$\frac{164.15}{12}=13.68$ dollars
