Answer:
-43.68
Step-by-step explanation:
Well, if the notebooks cost x, then you know that
3x + 45.87 = 60.54
right? so, solve for x. 60.54 - 45.87 = 14.67
Divide the difference by 3.
V•w = (-7i +4j)•(-6i +5j) = (-7)×(-6) +4×5 = 42 +20
v•w = 62
Answer:
So average of a set of values is the sum of given values divided by the number of values
So, in this case the given values are 12, 9 , 4 , 8 ,7 and x (letting the 6th friend's time be x)
so the average will be:
(12 + 9 + 4 + 8 + 7 + x)/6 = 9
40 + x = 54
x = 54 - 40
x = 14 hours
