Answer:
s = 0.3m
Step-by-step explanation:
Given that s varies directly with m then the equation relating them is
s = km ← k is the constant of variation
To find k use the condition
s = 9 when m = 30
9 = 30k ( divide both sides by 30 )
= k
s = m or
s = 0.3m ← equation of variation
The answer should be X= 19/5

Answer:
Step-by-step explanation:
Answer choices please
4 -8=9-6X
Move -6X to the other side, sign changes from -6X to +6X.
4X+6X-8=9-6X+6X
4X+6X-8=9
10X-8=9
Move 8 to the other side, sign changes from +8 to -8.
10X-8=8=9+8
10X=17
divide by 10 for both sides
10X/10=17/10
X=17/10 or X= 1 7/10
Answer: X=17/10 or X= 1 7/10
