AQ : QE = 2 : 1 ( property of a centroid of a triangle)
Therefore 2/1 = 18 / QE
2QE = 18
QE = 9 (answer)

Let's solve this inequality!

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:

Now, move 20 to the right, using the opposite operation:

Subtract:

Divide both sides by -1 to isolate x:
(Answer)
_____________
<em>Additional comment</em>
When we divide both sides of an inequality by a negative number, we flip the inequality sign.

The result of simplifying each number (-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃ using the exponent rules is -3
To solve this exercise we have to resolve algebraic operations following the exponent rules.
(-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃
Using the product rule that indicates that: the exponent result will be the addition of these exponents, we have:
(-3)¹/₃⁺ ¹/₃ ⁺ ¹/₃
(-3)³/₃
(-3)¹
-3
<h3>What is an exponent?</h3>
In mathematics an exponent is the number of time that a number, called (base) is multiplied by itself. It is also called, power or index.
Example: 3² = 3*3 = 9

Given <span>-2.8k-4.31=-15.79 :
1) Isolate the "k" term on the left by adding 4.31 to both sides of this equation.
2) Simplify the right side.
3) Divide both sides by -2.8 and you'll have the answer: k = ?</span>
