5 - x = 12
We're essentially just trying to get "x" onto its own side.
So, simply subtract 5 from both sides.
-x = 12 - 5
Simplify.
-x = 7
Now, divide both sides by -1.
x = -7

Answer:
47 miles
Step-by-step explanation:
The formula for Mean = Sum of values/Number of values
Number of values is 6
From the above question, we are only given 5 values,
The 6th value is represent as= x
Hence,
60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles/6 = 59 miles
Cross Multiply
60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles = 6 × 59 miles
307 miles + x miles = 354 miles
x miles = 354 miles - 307 miles
x miles = 47 miles
Therefore, the number of miles he need to run on day 6 is 47 miles

Step-by-step explanation:
<u>Step 1: Define</u>
2x < -10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 2 on both sides: x < -5
Here we see that any value <em>x</em> smaller than -5 would work as a solution.
<u>Step 3: Identify</u>
<em>Answer choices.</em>
I. -2
II. 2
III. 10
We see that none of these numbers are less than -5. Therefore, non of the answer choices are correct.
Plot a point at "-9" and the other at "7". Both dots will be shaded in.
