Answer: 45
Step-by-step explanation: The range is the difference between the greatest number in the data set and the least number in the data set which in this case is 99 - 54 or 45. So the range of this data set is 45.
Answer:
12 = -3 - 3x
Step-by-step explanation:
Same concept as the last question I answered. First, let's derive a formula from the given model. So we have 3 negative x and 3 negative 1 which equal to 12 positive ones, this can be written as:
-3x - 3 = 12
which can be rewritten as
12 = -3 - 3x
Answer:
<h3>x^2+3x-12/(x+3)(x-5)(x+7)
</h3>

Answer:
43/12
Step-by-step explanation:
First we must find a common denominator for all 3 fractions, 1/2 cup, 2 1/3 cup, and 3/4 cup all share 12 as a common denominator.
However, let's convert 2 1/3 cup into an improper fraction: there are 2 (3/3 cups) here multiply (3/3) and (2/1) you get 6/3. Finally, add the remaining 1/3 to 6/3 and you get 7/3.
Now, to get all these fractions to have the same common denominator.
(1/2) ×(6/6)=(6/12)
(7/3)×(4/4)=(28/12)
(3/4)×(3/3)=(9/12)
Add them all together and your answer is: (43/12)
Answer:
common factors of 20 are 20,10,5,4,2,1
common factors of 100 are 100,50,25,20,10,5,2,1.The common factors of 20 and 100 are20,10,5,4,2,1, interesting the two sets above.
