Solve the inequality and enter your solution as an inequality comparing the variable to the solution in the box below. 18 + x &g
storchak [24]

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

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

<em><u>x>24</u></em>

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

<em><u>Step-by-step explanation:</u></em>

First, you switch sides.

x+18>42

Then, you subtract by 18 from both sides of an equation.

x+18-18>42-18

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

42-18=24

<u><em>Final answer is x>24</em></u>

I hope this helps you!

Have a nice day! :)

List P contains m numbers; list Q contains n numbers. If the two lists are combined to produce list R, containing m + n numbers,
Anarel [89]

Answer: YES

Step-by-step explanation:

We need to write out the expressions

P= {m}

Q= {n}

R= {m+n}

If 2m=n then we can say;

P= {½n} Q= {n} & R= {³/²n}

It is obvious that the smaller number in Q is greater than the largest number in P

We can make some assumptions.

Let n= (x,y,z)

Consequently,

P={½x,½y,½z} Q={x,y,z} and R= {1.5x,1.5y,1.5z}

Therefore the median will be the middle element,

Median of P= ½y

Median of Q = y

Median of R = 1.5y

And 1.5y>1.5y

Then we can agree that the median of R is greater than the median of both P and Q
