<u><em>Hi there! </em></u>

<u><em>Answer:</em></u>

<u><em>X>1</em></u>

<u><em>*The answer must have a positive sign and greater than symbol.*</em></u>

Step-by-step explanation:

First, you subtract by 3 from both sides of an equation.

2x+3-3>5-3

Then, you subtract by the numbers from left to right.

5-3=2

2x>2

You can also divide by 2 from both sides of an equation.

\frac{2x}{2}>\frac{2}{2}

Finally, you divide by the numbers from left to right.

2/2=1

<em><u>Final answer is x>1</u></em>

I hope this helps you!

Have a nice day! :)

:D

Thank you so much! :)

<h2>Greetings!</h2>

Answer:

x > 1

Step-by-step explanation:

Firstly, the +3 must be moved over to the other side, making it a -3:

2x > 5 - 3

2x > 2

Then, divide both sides by two to get 1x:

x > 1

The physical plant at the main campus of a large state university receives daily requests to replace fluorescent light bulbs. Th
ankoles [38]

We have been given that the distribution of the number of daily requests is bell-shaped and has a mean of 38 and a standard deviation of 6. We are asked to find the approximate percentage of lightbulb replacement requests numbering between 38 and 56.

First of all, we will find z-score corresponding to 38 and 56.

z=\frac{x-\mu}{\sigma}

z=\frac{38-38}{6}=\frac{0}{6}=0

Now we will find z-score corresponding to 56.

z=\frac{56-38}{6}=\frac{18}{6}=3

We know that according to Empirical rule approximately 68% data lies with-in standard deviation of mean, approximately 95% data lies within 2 standard deviation of mean and approximately 99.7% data lies within 3 standard deviation of mean that is -3\sigma\text{ to }3\sigma.

We can see that data point 38 is at mean as it's z-score is 0 and z-score of 56 is 3. This means that 56 is 3 standard deviation above mean.

We know that mean is at center of normal distribution curve. So to find percentage of data points 3 SD above mean, we will divide 99.7% by 2.

\frac{99.7\%}{2}=49.85\%

Therefore, approximately 49.85\% of lightbulb replacement requests numbering between 38 and 56.

4x + 3y = 6<br> -4x + 2y = 14<br> Solve the system of equations.
pshichka [43]

Answer:

x = -1.5    y = 4

Step-by-step explanation:

4x + 3y = 6

-4x + 2y = 14                  Add both equations together

       5y = 20                  Divide both sides by 5

        y = 4

Plug this into one of the original equations

4x + 3(4) = 6                Multiply

4x + 12 = 6

     -12  - 12                  Subtract 12 from both sides

4x = -6                         Divide both sides by 4

x = -1.5
