Answer:

15

Explanation:

If y varies inversely as x, the two variables can be represented in an equation in the form y=kx where k is some constant.

We are given that y=5 when x=6. We can plug this into the above equation to find what k is:

5=k6

30=k

Based on this we can create our equation:

y=30x

And then find x when y=2:

2=30x

2x=30

x=15

Pleasee help!! “It costs $2.75 to buy 3/4 lb of grapes. How much would it cost to purchase 9.5 lbs of grapes? Explain or show yo
avanturin [10]

Answer:

$34.83

Step-by-step explanation:

First convert 3/4 to decimal form: 3/4 = 0.75

Create a proportion using similar rates:

$2.75 / 0.75 lb  = x / 9.5 lb

where "x" represents the price of the 9.5 lbs of grapes we need to find.

Solve for x by multiplying both sides by 9.5 lb to isolate x completely

2.75 * 9.5 / 0.75 = x

Therefore x = $34.83
