It would be: 20/7 = 2 6/7
In short, Your Answer would be 2 6/7
Hope this helps!
Answer:
y = 28
Step-by-step explanation:
Given that y varies directly as x and inversely as z then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 4 when x = 2 and z = 7, then
4 =
( multiply both sides by 7 )
28 = 2k ( divide both sides by 2 )
14 = k
y =
← equation of variation
When x = 6 and z = 3 , then
y =
= 14 × 2 = 28
Answer:
a = 
Step-by-step explanation:
To find the value of a, find the Slope of both the equations.
For lines to be perpendicular to each other 
For line 1:
2x + 3y − 6 = 0 represent the line in y=mx +c form
3y = -2x + 6
y =
+ 
y =
+ 2
= 
For line 2:
ax - 3y = 5
ax = 5 + 3y
ax - 5 = 3y
y = 
= 
Apply the condition of perpendicularity:
*
= - 1

a = 
where are the anglessssssssss
