Zanzabum

Answer:

x = -3

Step-by-step explanation:

12 -4x-5x = 39

Combine like terms

12 - 9x = 39

Subtract 12 from each side

12-9x-12 = 39-12

-9x = 27

Divide by -9

-9x/-9 = 27/-9

x = -3

The following table shows the speeds at which Jeff does 4 activities. For example, biking has a rate of 19 miles in 2 hours. Whi

ExtremeBDS [4]

The type of activity that Jeff does at a speed of 4.5 miles per hour is Swimming

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem !

<em>This problem is about Kinematics.</em>

We will solve it in the following way

$\texttt{Speed of Biking} = \texttt{Distance of Biking} \div \texttt{Time Taken}$

$\texttt{Speed of Biking} = \texttt{19} \div \texttt{2}$

$\texttt{Speed of Biking} = 9.5 \texttt{ miles per hour}$

$\texttt{ }$

$\texttt{Speed of Walking} = \texttt{Distance of Walking} \div \texttt{Time Taken}$

$\texttt{Speed of Walking} = \texttt{14} \div \texttt{4}$

$\texttt{Speed of Walking} = 3.5 \texttt{ miles per hour}$

$\texttt{ }$

$\texttt{Speed of Running} = \texttt{Distance of Running} \div \texttt{Time Taken}$

$\texttt{Speed of Running} = \texttt{15} \div \texttt{3}$

$\texttt{Speed of Running} = 5 \texttt{ miles per hour}$

$\texttt{ }$

$\texttt{Speed of Swimming} = \texttt{Distance of Swimming} \div \texttt{Time Taken}$

$\texttt{Speed of Swimming} = \texttt{18} \div \texttt{4}$

$\texttt{Speed of Swimming} = \boxed{4.5 \texttt{ miles per hour}}$

$\texttt{ }$
