-18/9 = 2, 9 goes into 18, 2 times, but a negative divided by a positive always = a negative number so the answer would come out to be -2.

however is you were typing -1.8 / 9 then it would be -0.2. Multiplying -0.2 * 9 would give you -1.8. Same rule applies as to why it's negative

I wasn't sure if the comma was a typo in your question but I Hope this helps :)

2/3 *4/4 = 8/12

1/4 *3/3 = 3/12

2/3 +1/4

8/12+3/12

Sydney and Mila go to the movie theater and purchase refreshments for their friends. Sydney spends a total of $28.50 on 9 drinks

iogann1982 [59]

The system of equations that can be used to find the price of one drink and the price of one bag of popcorn is:

9x + 2y = 28.50

5x + 10y = 42.50

The price of a bag of popcorn is $3.00

Step-by-step explanation:

Sydney and Mila go to the movie theater and purchase refreshments for their friends

Sydney spends a total of $28.50 on 9 drinks and 2 bags of popcorn
Mila spends a total of $42.50 on 5 drinks and 10 bags of popcorn

We need to write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn and using these equations, to determine and state the price of a bag of popcorn

Assume that the price of each drink is $x and the price of each bag of popcorn is $y

∵ Sydney spends a total of $28.50 on 9 drinks and 2 bags of popcorn

∵ The price of each drink is $x

∵ The price of each bag of popcorn is $y

- Multiply 9 by x and 2 by y, add the products and equate the

sum by 28.50

∴ 9x + 2y = 28.50 ⇒ (1)

∵ Mila spends a total of $42.50 on 5 drinks and 10 bags of popcorn

∵ The price of each drink is $x

∵ The price of each bag of popcorn is $y

- Multiply 5 by x and 10 by y, add the products and equate the

sum by 42.50

∴ 5x + 10y = 42.50 ⇒ (2)

The system of equations that can be used to find the price of one drink and the price of one bag of popcorn is:

9x + 2y = 28.50

5x + 10y = 42.50

Lets solve the system of equations

∵ 9x + 2y = 28.50 ⇒ (1)

∵ 5x + 10y = 42.50 ⇒ (2)

- Multiply equation (1) by -5 to eliminate y

∵ -45x - 10y = -142.50 ⇒ (3)

Add equations (2) and (3)

∴ -40x = -100

- Divide both sides by -40

∴ x = 2.5

Substitute the value of s in equation (1) or (2) to find y

∵ 9(2.5) + 2y = 28.50

∴ 22.5 + 2y = 28.50

- Subtract both sides by 22.5

∴ 2y = 6

- Divide both sides by 2

∴ y = 3

The price of a bag of popcorn is $3.00

Kristina used synthetic division to divide the polynomial f(x) by x−2, as shown on the table. What is the value of f(2)? −14 −11

UNO [17]

Answer:

-11

Step-by-step explanation:

The answer to the first one sould be -11

2x^3 +5x^2−x−6

Write 5x^2 as 4x^2 + x^2......and we have.....

2x^3 + 4x^2 + x^2 - x - 6

2x^2 ( x + 2) + ( x + 2)(x - 3)

(x + 2) [ 2x^2 + x - 3]

(x + 2) (2x +3) (x - 1)

x^3−4x^2−3x+18 = 0

Using some synthetic division, we have

3 [ 1 - 4 -3 18 ]

3 -3 -18

_______________

1 -1 -6 0

The remaining polynomial is x^2 - x - 6 which factors as (x - 3) ( x + 2)

So .... the factored form is (x - 3) ( x - 3) ( x + 2) = ( x + 2) ( x - 3)^2 = 0

How are common denominator and a common multiple alike and different

zimovet [89]

A common denominator is when 2 fractions have the same denominator and a common multiple is when two multiples have at least 1 number alike. They are alike because they need to have a number in common and they are different because a common denominator has to do with fractions and a common multiple has to do with multiples.
