In this question, it is given that y varies inversely as x . So the equation is

y = \frac{k}{x}

And here k is the proportionality constant .

And when x=6, y=12

12 = \frac{k}{6}
\\
k =72

So the values of the proportionality constant k is 72 and the correct option is B.

What is bigger 9/10 or 7/8
Nataliya [291]
You start by cross multiplying:
9 x 8 = 72
This is considered the fraction on the left's value.
You do the same for the other side:
10 x 7 = 70
This is considered the value of the fraction 7/8
72 has a greater value than 70.

Therefore, 9/10 is larger.

7 2\3+ (5 1\6-1 5\9)
lorasvet [3.4K]
Start off with: 5 1/6 - 1 5/9
turn it into an entire fraction: 31/6 - 14/9
make a common denominator (which is 18): 93/18 - 28/18 = 93 - 28 = 65/18
65/18 + 7 2/3 is the new equation
7 2/3 = 23/3
23/3 = 138/18
65/18 + 138/18 = 203/18
Simplify: 203/18 = 11 5/18
Answer: 11 5/18
