Both expressions are related because 12 divided by 4 equals to 3, and 1/4 of 12 equals to 3 too.
D. how close a measurement is to an accepted value for the measurement
By solving an absolute value equation, we will see that the two solutions are:
x = 49 and x = -41
<h3>
How to solve the equation for x?</h3>
First, we need to write the equation, we will get:
(1/5)*|x - 4| - 3 = 6
That is an absolute value equation, first let's isolate the absolute value part on the left side, so we get:
(1/5)*|x - 4| = 6+ 3 = 9
|x - 4| = 9*5 = 45
Now we have the simpler equation:
|x - 4| = 45
Which can be written in two ways:
x - 4 = 45
x - 4 = -45
So we will have two solutions for x:
x = 45 + 4 = 49
x = -45 + 4 = -41
These are the two possible values of x.

To solve it for "a" is to isolate "a' in one side, by doing some algebraic operations.
U =ak -b
1) Let's rewrite it
-b+ak=u
2) Add b to both sides
-b +b +ak = u +b
ak = u+b
3) Divide both sides by k
4) Finally, we have it for 'a':
Hello:
<span>4 números inteiros consecutivos: n , (n+1) , (n+2) , (n+3)
</span><span>A soma de 4 números inteiros consecutivos é 326 :
