Here is a set of 5 numbers that give a mean of 17.25.
Answer:
14, 11, 16, 21, 24.25
To find the different ways to display the boxes, you will find all the different ways you can make an array of 12.
12 x 1 and 1 x 12
2 x 6 and 6 x 2
3 x 4 and 4 x 3
There are 6 possibilities.
207$ - 15$ = 192$
192$ : 8 = 24$
Answer: Each book costed 24$.
You said 2x - 9 < 7
Add 9 to each side: 2x < 16
Divide each side by 2 : x < 8 .
-5(2x+1)-2x-2=17
first, distribute
-10x-5-2x-2=17
combine like terms
-12x-7=17
get the x alone, eliminate the constant
-12x=24
divide out the -12 to get the x alone.
x=-2
