Answer: Yes A is correct
Step-by-step explanation:
Multiply the first equation by 3...
2x+3y=k+1 needs to be subtracted by 3x+3y=3k
which equals -x=-2k-1
Then you can multiply the equation by -1 to make them all positive. Resulting in x=2k+1
Answer:

Answer:
Step-by-step explanation:
If r varies directly with the square of m and inversely as s,
then 
where k is some constant
Given r = 12 when m = 6 and s = 4:
⇒ 
⇒ 
⇒ k = 
Therefore, substituting the found value of k into the original equation: 
Find r when m = 4 and s = 10:
⇒ 
⇒
the answer is 5.411.
