PLEASE HELP WILL MARK BRAINLIEST!!!

Answer 1

Answer:

B

Step-by-step explanation:

given x varies inversely with y, the the equation relating them is

x = $\frac{k}{y}$ ← k is the constant of variation

To find k use the condition x = 6 when y = 10, hence

k = xy = 6 × 10 = 60

x = $\frac{60}{y}$ ← equation of variation

When x = 8, then

8 × y = 60 ( divide both sides by 8 )

y = $\frac{60}{8}$ = 7.5 → B
