<h3>Answer: k - 9</h3>

We have some number k and we take 9 from it to end up with k-9, which represents 9 less than k.

For example, if k = 12, then k-9 = 12-9 = 3. So 3 is nine less than the number k = 12.

Joseph's lunch at a restaurant costs 13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax

Musya8 [376]

Answer:

The cost before tax with tip is $15.21.

Step-by-step explanation:

To calculate percentage, take the percent (17%) and take its decimal form. This means 17% is 0.17 (like 50% would be 0.5). multiply the number you want the percentage of by the decimal form. 13*0.17=2.21. Add this to the cost before tax and before tip. 13.00+2.21=15.21. The cost before tax with tip is $15.21.

what is the quotient (65y3 15y2 − 25y) ÷ 5y? a. 13y2 3y − 5 b. 13y3 3y2 − 5y c. 13y2 − 3y 5 d.13y2 − 3y − 5

Keywords:

<em>Division, quotient, polynomial, monomial </em>

For this case we must solve a division between a polynomial and a monomial and indicate which is the quotient.

By definition, if we have a division of the form: $\frac {a} {b} = c$ , the quotient is given by "c".

We have the following polynomial:

$65y ^ 3 + 15y ^ 2 - 25y$ that must be divided between monomy $5y$ , then:

$C (y)$ represents the quotient of the division:

$C (y) = \frac {65y ^ 3 + 15y ^ 2 - 25y} {5y}$

$C (y) = \frac {65y ^ 3} {5y} + \frac {15y ^ 2} {5y} - \frac {25y} {5y}$

$C (y) = 13y ^ 2 + 3y-5$

Thus, the quotient of the division between the polynomial and the monomial is given by:

$C (y) = 13y ^ 2 + 3y-5$

Answer:

The quotient is: $C (y) = 13y ^ 2 + 3y-5$

Option: A
