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
|2*-20| - 30= |-40| - 30= 40-30=10
|30*5| - |(-20*(5)|= |150| - |100|= 150-100= 50

Answer:
250.9
Step-by-step explanation:
1) Add all the numbers = 2007
2) Divide by the number of integers present = 2007/8
3) Round to the nearest tenth = 2007/8 = 250.875 = 250.9
