If the average of x and y is 11 and the average of x, y and z is 5, what is the value of z?
1 answer:
Answer:
z = -17
Step-by-step explanation:
If the average of x and y is 11, then;
x+y/2 = 11
x+y = 2 + 11
x+y = 22 .... 1
similarly, if average of x, y and z is 5, then;
x+y+z/3 = 5
x+y+z = 3*5
x+y+z = 15
Since x+y = 22
22 + z = 5
z = 5 - 22
z = -17
Hence the value of z is -17

1.80 this is the correct answer
Simplified answer would be 60k^2+k
and you get that answer by combining like terms, Good Luck!
Slope = (y2 - y1)/(x2 - x1)
Slope = (212 - 32)/(100 - 0)
Slope = 180 / 100
Slope = 18/10
Slope = 9/5
Answer
D. slope = 9/5
