You would add up all of the numbers and then divide them by 5 since you have a total of 5 different sets of numbers (To get the mean). Then you have to find the median by putting all of the numbers in numerical order and get the number in the middle. Finally you subtract the median from the mean and you end up getting “B” as your answer.
Answer:
-2(9x-8)
Step-by-step explanation:
We are to simplify the expression -3.1x+7-7.4x-1.5x-6(x-3/2)
Open the parenthesis
-3.1x+7-7.4x-1.5x-6(x-3/2)
= -3.1x+7-7.4x-1.5x-6x+6(3/2)
= -3.1x+7-7.4x-1.5x-6x+9
Collect like terms
= -3.1x-7.4x-1.5x-6x+7+9
= -12x-6x+16
= -18x+16
= -2(9x-8)
Hence the simplified form of the expression is -2(9x-8)
Answer:
8
Step-by-step explanation:
When you add 2 negatives you get a negative for example -5+-15= -20 when you add a positive to a negative it increases the number for example -20+7= -13. Hope this helps
