Step-by-step explanation:
Given that,
a. x = 15 and y = 14
The equation is :
x = ky
or
[tex]k=\dfrac{x}{y}[/tex]
Put all the values,
[tex]k=\dfrac{15}{14}\\\\k=1.07[/tex]
b. Now, put y = 70 and k = 1.07.
x = 1.07×70
x = 74.9
c.
Put x = 45 and k = 1.07.
[tex]y=\dfrac{x}{k}\\\\y=\dfrac{45}{1.07}\\\\y=42.05[/tex]
Hence, this is the required solution.
