Answer:

x² + 2x + 9 - \frac{7}{x+3}

Step-by-step explanation:

Using Synthetic division

- 3 |   1    5     15   20

       ↓  - 3   - 6    - 27

     ----------------------------

       1     2      9     - 7 ← remainder r(x)

Quotient Q(x) = x² + 2x + 9

Thus

x³ + 5x² + 5x + 20 = x² + 2x +9 - \frac{7}{x+3}

A total of 267 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student t
Anestetic [448]

Answer:

the number of adult tickets sold is

x = 89

and , the number of student tickets sold is y = 178

Step-by-step explanation:

Let the number of adult tickets sold be x and number of student tickets sold be y !

<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em> Total 267 tickets were sold

i.e, x + y = 267

x = 267 - y .... ( i )

Also, The number of student tickets sold was two times the number of adult tickets sold.

i.e, y = 2x ...... ( ii )

putting value of x from ( i ) in ( ii )

y = 2 ( 267 - y )

y = 534 - 2y

3y = 534

y = 534/3

y = 178

also, x = 267 - y

x = 267 - 178

x = 89

So, the number of adult tickets sold is

x = 89

and , the number of student tickets sold is y = 178

Drupady [299]

Answer: its is 300 hope this helps Pls give me brainly

Step-by-step explanation: Remember that the tens place is two moves from the left of the decimal point (if it exists). To round to the nearest ten (nearest 10), we use the whole numbers place to determine whether the tens place rounds up or stays the same.

Solution steps:

Step 1: Locate and underline the ten place (0) and look to the right (3):

303

Step 2: The digit to the right (3) is 4 or below. So, we replace it by a 0 (zero), then we get 300 as the answer.

In short: 303 rounded to the nearest ten is 300.
