Let the constant of variation be c.
We are given that y varies inversely with 2.5x, this means that:
y = (c) / (2.5x)
This can be written as:
2.5xy = c
Now, we a re given that y = 5.6 at x = 30.
Substitute with these values in the equation to get the value of c as follows:
2.5xy = c
2.5(30)(5.6) = c
c = 420
Therefore, the equation that describes the relation is:
2.5xy = 420
Answer:
Step-by-step explanation:
Distance between earth and moon in meters = 386400 x 10³ m
Speed of ship = 11184.7258 m / s
Time taken = distance of moon from earth / speed of ship
= 386400 x 10³ / 11184.7258
= 34.5471 x 10³ s
= 34.5471 x 10³ / 60 x 60 hour
= 9.596 hours

Step-by-step explanation:
65x+105=y
Substitute 6 for x to find the cost for 6 classes
65(6)+105=y
390+105=y
495=y
