Answer:
x = - 6
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 9 when x = 3, thus
k = 
= 
= - 3
y = - 3x ← equation of variation
When y = 18, then
18 = - 3x ( divide both sides by - 3 )
x = - 6
Answer:
37.17
Step-by-step explanation:
Find the mean by adding together all of the numbers, then dividing it by how many numbers there are.
(29 + 75 + 21 + 45 + 39 + 14) / 6
= 37.17
So, if 29 is added, the mean is approximately 37.17
