5x ÷ x² - 9 + 7 ÷ x + 3

Write the division as a fraction:

\frac{5x}{x^{2} }\\ - 9 + \frac{7}{x} + 3

Simplify the expression:

\frac{5}{x} - 9 + \frac{7}{x} + 3

Calculate the sum:

\frac{5}{x} - 6 + \frac{7}{x}

Write all numerators above the common denominator:

\frac{5 - 6x + 7}{x}

Add the numbers and you get the final answer:

\frac{12-6x}{x}

It took me 3 hours to visit my friend in Maine, averaging a speed of 58 miles per hour. If it took me 15 minutes less to get bac
mariarad [96]

Answer:

<u>The average speed coming home was 63.27 miles per hour</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed from home to Maine = 58 miles per hour

Time of the first leg of the trip = 3 hours or 180 minutes

Time of the second leg of the trip = 15 minutes less = 180 - 15 = 165 minutes or 2 hours 45 minutes

2. What was my average speed coming home?

Let's calculate the distance from home to Maine, this way:

Speed = Distance/Time

Distance = Speed * Time

Distance = 58 * 3 = 174 miles

Now, let's calculate the speed of the second leg, as follows:

Speed = Distance/Time

2 hours 45 minutes = 2.75

Speed = 174/2.75

<u>Speed = 63.27 miles per hour</u>
