To compare these numbers, you must first put them into one format. Since you have mixed numbers, you may have to find and use the LCD.
-2.5, 1/5, 10, -12/4, 18/5, 10 could be simplified somewhat immediately:
-2.5, 1/5, 10, -3, (3 3/5) This set of numbers is simple enough so that you could rearrange them in ascending order mentally:
-3, -2.5, 1/5, (3 3/5), 10
In this case the number of elements in this set is odd, so all you have to do is to select the MIDDLE element: 1/5.
The median is 1/5.
You MUST learn this procedure (arranging the set elements in ascending order and selecting the middle element) so that you can apply it yourself.
Answer:
f(-10) = 2 times -10 + 1
= -19
f(2) = 2^2
= 4
f(-5) = 2 times -5 + 1
= -9
f(-1) = (-1)^2
= 1
f(8) = 3-8
= -5
Step-by-step explanation:
Answer:
Exact Form:
11/ 5
Decimal Form:
2.2
Mixed Number Form:
2 1/
5
Step-by-step explanation:
For the decimal, divide 11 by 5.
To get the Mixed number form, find out how many times 5 goes into 11, then then what is left over. Put the number left over the number that was dividing. 5 goes into 11 2 times, then 1 is left over, put the 1 over 5.
Answer:
4 < x < 14
Step-by-step explanation:
The third side is between the difference and the sum of the other two sides
9-5 < x < 9+5
4 < x < 14
Answer:
x = -1
Step-by-step explanation:
First, add x to both sides.
-2x-6-x+x=-x-4x-8+x
-----------------------------------
Next, Refine it.
-2x - 6 = -4x - 8
--------------------------------------
Now, add 6 to both sides.
-2x - 6 + 6 = -4x - 8 + 6
--------------------------------------
Now we Simplify.
-2x = -4x - 2
---------------------------------------
Add 4x to both sides.
-2x + 4x = -4x - 2 + 4x
----------------------------------------
Simplify again.
2x = -2
-----------------------------------------
Divide both sides by 2.
2x/2 = -2/2
------------------------------------------
And we're almost finish! Just need to simplify.
x = -1.
