Answer:
x = - 36
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 27 when x = 12, then
k = yx = 27 × 12 = 324, thus
y = 
← is the equation of variation
When y = - 9, then
- 9 = ( multiply both sides by x )
- 9x = 324 ( divide both sides by - 9 )
x = - 36
Answer:
x = 
= 2 
Step-by-step explanation:
34.2 = 13.4 + 9.6x
20.8 = 9.6x
x = 20.8 / 9.6
x =
Answer:
I can't understand what you wrote but I think it's 594
Step-by-step explanation:
You divide 12 by 2, it is igual to 6.
6 x 33 = 189
189 x 3 = 594
I try to help if it not work :(
