Question

x=ky a. if x=15 when y=14.find the value of k.. b..Find x when y=70 c...find y when x=45​

Answer 1

Explanation:

Given that,

a. x = 15 and y = 14

The equation is :

x = ky

or

`k=(x)/(y)`

Put all the values,

`k=(15)/(14)\\\\k=1.07`

b. Now, put y = 70 and k = 1.07.

x = 1.07×70

x = 74.9

c.

Put x = 45 and k = 1.07.

`y=(x)/(k)\\\\y=(45)/(1.07)\\\\y=42.05`

Hence, this is the required solution.
