Answer:
I think that it D
Step-by-step explanation:
C= .07=70%. So I know that it is not C
A= 30% but the question doesn't even have a 3 in it, so therefore it cannot be A.
B= Is basically the same concept as A. There is no .3 or 3 peroid.
So I say D
Answer:
52
Step-by-step explanation:
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
