Answer:
I looked it up and it said 0.5
180
Because 120 divided by 2 is 60.
And 120 + 60 is 180
To find the mean (average), u add up all the numbers, then divide by how many numbers there are.
(200 + 150 + 325 + 100 + 75) / 5 = 850/5 = 170 <== the mean
If you follow PEMDAS
P-parentheses
E-exponent
M-multiplication
D-divide
a-addition
s-subtraction
then you should look in the parentheses and multiplying 3x should be your first step IF you know x
hope this helps :)
It would be D. 5/20 because the other 2 you would add then subtract and then you would just put the answer yo get from subtracting it over 20.
