Answer:
The range is 500 :)
Step-by-step explanation:
the range is the difference between the largest number, in this case 600 and the smallest number, 100. So you do 600-100 which gives you 500.
Answer: The average age is 7.1 years.
This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.
To start, lets multiply the total number of children by their individual ages.
6 x 5 = 30 years
14 x 8 = 112 years
There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.
The correct answer is: x < 1.25
To solve this, we following the same steps as when solving inequalities. We just have to remember to reverse the sign if we multiply or divide by a negative number.
-1.2x - 8.2 > -9.7
-1.2x > -1.5
x < 1.25
Answer:
40 centimeters square.
Step-by-step explanation:
Area= length × width
8×5=40
Have a nice day
Answer:
g = 7/2
Step-by-step explanation:
-5 + 7g = 3g + 9
~Add 5 to both sides
7g = 3g + 14
~Subtract 3 to both sides
4g = 14
~Divide 4 to both sides
g = 14/4 or g = 7/2
Best of Luck!
