Answer:

x < 0.128

Step-by-step explanation:

The inequality given is:

4.2x + 5.6 < 7.2 - 8.3x

Let us collect like terms:

4.2x + 8.3x < 7.2 - 5.6

12.5x < 1.6

=> x < 1.6/12.5

x < 0.128

A=pir^2 solve for pi
VashaNatasha [74]

Given problem;

   A = \pi r²

   Solve for π;

To solve for π implies that we make it the subject of the expression.

So;

       A = π r²

      Now multiply both sides by \frac{1}{r^{2} }

 So;

                A x \frac{1}{r^{2} }   = \pi x r² x \frac{1}{r^{2} }

              r² cancels out from the right side and leaves only π;

                  π = \frac{A}{r^{2} }

So    \pi  = \frac{A}{r^{2} }

X-23 / x^2 -x- 20 - 2/5-x
alexira [117]

By simplifying \[x - \frac{{23}}{{{x^2}}} - x - 20 - \frac{2}{5} - x\] . This will result in a simplified version of  \[ - \frac{{5{x^3} + 102{x^2} + 115}}{{5{x^2}}}\].

The Simplifying Algorithm is a wonderful way to simplify complex mathematics problems. It can be used to solve equations, convert fractions to decimals, and perform many other math operations. In this problem, the Simplifying Algorithm will help you reduce \[x - \frac{{23}}{{{x^2}}} - x - 20 - \frac{2}{5} - x\]

Since two opposites add up to 0, remove them from the expression.

\[ - \frac{{23}}{{{x^2}}} - \frac{{102}}{5} - x\]

Write all numerators above the least common denominator 5x2

\[ - \frac{{115 + 102{x^2} + 5{x^3}}}{{5{x^2}}}\]

Use the commutative property to reorder the terms so that constants on the left

\[\frac{{ - 5{x^3} - 115 - 102{x^2}}}{{5{x^2}}}\]

Rearrange the terms

\[\frac{{ - 5{x^3} - 102{x^2} - 115}}{{5{x^2}}}\]

By reording the terms

\[ - \frac{{5{x^3} + 102{x^2} + 115}}{{5{x^2}}}\]

Hence, by simplifying this equation, divide both numerator and denominator. This will result in a simplified version of  \[ - \frac{{5{x^3} + 102{x^2} + 115}}{{5{x^2}}}\].
