Answer:

x = -27

Step-by-step explanation:

Step 1 :

Equation at the end of step 1 :

(5 • (x + 3)) - 4 • (x - 3) = 0

Step 2 :

Equation at the end of step 2 :

5 • (x + 3) - 4 • (x - 3) = 0

Step 3 :

Equation at the end of step 3 :

x + 27 = 0

Step 4 :

Solving a Single Variable Equation :

4.1 Solve : x+27 = 0

Subtract 27 from both sides of the equation :

x = -27

One solution was found :

x = -27

Answer:

$5(x + 3) = 4(x - 3) \\ 5x + 15 = 4x - 12 \\ 5x - 4x = - 15 - 12 \\ x = - 27$

The table shows the distance Randy drove on one day of her vacation

horsena [70]

Given the table showing the distance Randy drove on one day of her vacation as follows:

$\begin{tabular}
{|c|c|c|c|c|c|}
Time (h)&1&2&3&4&5\\[1ex]
Distance (mi)&55&110&165&220&275
\end{tabular}$

The rate at which she travels is given by

$rate= \frac{distance}{time} \\ \\ = \frac{55}{1} =55mi/h$

If Randy has driven for one more hour at the same rate, the number of hours she must have droven is 6 hrs and the total distance is given by

distance = 55 x 6 = 330 miles.

What is the x please answer me quick

nordsb [41]

First u do a squared +b squared =c squared aka pythagorean theorem then so u already have c squared so you would do 5x5=25 and 13x13=169 so then the equation would be 25+?=169 then do 169-25 which equals 144 and then do the square root of that which is 12 THE ANSWER IS 12
