For this case we have the following inequality:
 - \frac{1}{2}x \ \textgreater \  6
 We multiply both sides of the equation by -1.
 By doing this, change the symbol of the inequality.
 We have then:
 \frac{1}{2}x\ \textless \ -6
 From here, we clear the value of x.
 We have then:
 x \ \textless \ (2) (- 6)

 x \ \textless \ -12
 
 Answer:
 The solution set is:
 
{x | x R, x < -12}

A cubic box is completely filled with 2,179 g of water. What is the length of one side of the box, in meters? m Explain your rea
Mazyrski [523]

Answer:

l\approx 1.296\,cm

Step-by-step explanation:

The water density is approximately 1 gram per cubic centimeter, which means that 1 gram of water occupies a volume of a cubic centimeter. Hence, 2.179 grams occupies a volume of 2.179 cubic centimeters.

Let assume volume occupied by the water has a cube-like shape, whose side has the following measure:

l = \sqrt[3]{2.179\,m^{3}}

l\approx 1.296\,cm
