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

<em>Roy</em>

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

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

<em>Alicia</em>

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

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

<em>Rickie</em>

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

Solve this equation <br> 3x-1/5-2/9x=124/5
Flauer [41]

Answer: x = 9

Step-by-step explanation:

1) Combine multiplied terms into a single fraction

2) Find a common denominator

3) Combine fractions with common denominator

4) Multiply from left to right (PEMDAS)

5) Multiply all terms by the same value to eliminate fraction denominators

6) Cancel multiplied terms that are in the denominator

7) Multiply again

8) Add _ to both sides

9)  Divide both sides by the same factor getting 125x/125 = 1125/125

10) Simplify, x = 9
