Answer:

2x^2 + 3x + 4

Step-by-step explanation:

generally, using long division,

(2x^3-3x^2-5x-12)/(x-3) = 2x^2 + 3x + 4

Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Alicia play

choli [55]

Answer:

Alicia is the golfer who has had the lowest number of strokes per hole

Step-by-step explanation:

we know that

The unit rate of the number of strokes per hole is equal to divide the number of strokes by the number of holes

Let

x ----> the number of strokes

y ----> the number of holes

we have

Roy

$x=42\ strokes\\y=9\ holes$

$\frac{x}{y}=\frac{42}{9}=4.67\ strokes\ per\ hole$

Alicia

$x=79\ strokes\\y=18\ holes$

$\frac{x}{y}=\frac{79}{18}=4.39\ strokes\ per\ hole$

Rickie

$x=123\ strokes\\y=27\ holes$

$\frac{x}{y}=\frac{123}{27}=4.56\ strokes\ per\ hole$

Compare

4.39 < 4.56 < 4.67

therefore

Alicia is the golfer who has had the lowest number of strokes per hole

Max has a science test on Thursday. On Monday he studied 2/9 of the material. On Tuesday he studied 1/4 of the remaining materia

wolverine [178]

Answer:

The answer to your question is:

Fraction he has review = 17/36

Fraction he have to study = 19/36

Step-by-step explanation:

Data

Monday studied = 2/9

Tuesday = 1/4

Fraction he has review = ?

Fraction he has left = ?

Process

As the denominator is 9, consider the whole is 9.

Then: Fraction left on Monday = 9/9 - 2/9

= 7 / 9

Fraction left on Tuesday = 7/9 - 1/4

= (28 - 9) / 36

= 19 / 36

Fraction he has review = 17/36

Fraction he have to study = 19/36

Price of movie ticket in Japan is x=7.362$

Price of movie ticket in Switzerland is y=13.652$

Step-by-step explanation:

Let, Price of movie ticket in Japan is x

Price of movie ticket in Switzerland is y

Statement 1 : Total of 79.39$ of three movie ticket in Japan and two movie ticket in Switzerland

We write, 3x+2y=79.39 ( Equation 1 )

Statement 1 : Total of 75.68$ of two movie ticket in Japan and three movie ticket in Switzerland

We write, 2x+3y=75.68 ( Equation 2 )

Solving by method of elimination

Multiplying equation 1 by 2, we get

6x+4y=158.78

Multiplying equation 2 by 3, we get

6x+9y=227.04

Subtracting both the linear equation,

6x+4y=158.78

- 6x+9y=227.04

_______________

0x-5y=(158.78-227.04)

-5y=(-68.26)

5y=68.26

y=13.652$

Replacing value of y in any equation

3x+2y=79.39

3x+2(13.652 )=79.39

x=17.362$

Thus,

Price of movie ticket in Japan is x=7.362$

Price of movie ticket in Switzerland is y=13.652$

I attached the document with the answers and work with the formulas. Since the formulas and fractions don't work very well with this site (especially the pi symbol, they should fix that).
