-3/4(4x+12)< - (2x+8)

Mathematics

Answer:

x>-1

Step-by-step explanation:

We will assume that here the question prompt us to solve the Inequality given and find the value of x for which is true and valid.

To begin with, let us re write our inequality clear as:

-\frac{3}{4}(4x+12)    Eqn(1).

Now, since this is an Inequality it must be noted that <em><u>for any operation of multiplication/devision</u></em> with a<u> </u><u><em>Negative number</em></u>, the order of the Inequality will change from ≤ to ≥ and vice versa.

So having said that, let us solve Eqn(1) and obtain a value for x as follow:

\frac{3}{4}(4x+12)>(2x+8)              Remove Negative sign from both signs and change order of inequality from < to >.

\frac{12}{4}x+\frac{36}{4}>2x+8                Factor Out Bracket on Left Hand Side

\frac{12}{4}x+\frac{36}{4}>\frac{8}{4}x+\frac{32}{4}             Make Common Denominator on Both Sides

12x+36>8x+32             Eliminate denominator to simplify and remove fractions

12x-8x>32-36             Gather equal terms on each side

4x>-4                              Simplify

x>-1                              Solve for x

<em>Thus solving the inequality gives that x is greater than -1:</em>

<em> i.e. </em>x>-1

Chip and dale are driving in a toy engine around the Christmas tree at a speed of 300 miles/hour. how many minutes will it take
Deffense [45]

Using proportions, it is found that it will take them 0.00248548 minutes to do one loop.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, according to their speed, in 60 minutes, they drive 300 miles. In how many minutes will they drive 20 m = 0,0124274 miles?

The <em>rule of three</em> is:

60 min - 300 miles

x min - 0.0124274 miles

Applying cross multiplication:

300x = 60 \times 0.0124274

x = \frac{60 \times 0.0124274}{300}

x = 0.00248548

It will take them 0.00248548 minutes to do one loop.
