Answer:  The required solution is x>0~\textup{or}~x

Step-by-step explanation:  We are given to find the solution of the following inequality:

|3x|>0~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know that,

If |x|>a, then we have

x>a~~~~~~\textup{or}~~~~~~x

From inequality (i), we get

|3x|>0\\\\\Rightarrow 3x>0~~~~~\textup{or}~~~~~3x\dfrac{0}{3}~~~~~~~~~~~~\Rightarrow 3x3~~~~~~~~~~~~~\Rightarrow x3~~~~~~~~~~~~~\Rightarrow x

Thus, the required solution is x>0~\textup{or}~x

V = 5² × 12 × π = 25 × 12π=300π m³

21. r = 14 ÷ 2 = 7

V = \frac{4}{3} \pi 7x^{3}

V = 457 1/3 π cm³

An equation is formed of two equal expressions. The number of people that can sit at a table is 6.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of people that can be seated at a table be represented by x, while the number of people that can be seated in a booth is y.

The equation for the two floor plans can be written as,

24x + 11y = 254

12x + 17y = 242

Solving the above equations, by plotting the two of the given equations. Therefore, the number of people that can sit at a table is 6.

Jill's mother limited her xbox 1 playing to 10 hours per week. she played on only four days, a different amount of time each day
Brrunno [24]
You have to find out how much time she played on Saturday, Wednesday, Friday, and Sunday. Let's look at the facts.
Sunday: No info is given.
Friday: She played the least of all four days
Saturday: Twice as much as Wednesday
Wednesday: No info is given.

We can write a problem and solve from this information. Let's use the variable W for Wednesday. Saturday is 2W. So whatever number Wednesday has, multiply it by 2. All of the total numbers should equal 10.

Since Friday was played the least amount, we know that every other day has to be at least 2 hours or above, so that Friday can be 1 hour. Sunday we have no info given.

This is a bit of guess and see for this problem. Let's say that Friday was 1 hour, Wednesday was 2, Sunday was 3, and Saturday was 4. Total that equals 10. Let's check to varify that these numbers are correct.

Friday was the least amount of hours of any day, which is why it is 1.
Wednesday had 2 hours, and Saturday had twice that many, which is 4.
Sunday has 3 hours.

In short, your answer would be: Friday 1 hour, Wednesday 2 hours, Sunday 3 hours, and Saturday 4 hours. I hope I explained it wel
