Question

Y varies directly as x. y=50 when x=5 find y when x=11????

Answer 1

Explanation:

given

y is directly to x

to remove directly we use constant let constant be k

y=k x. (1)

let calculate value of k

as it is given

y=50 when x=5

so put in above equation (1)

50=k(5)

50/5=k

10=k

now let find y when x =11

in above equation put the value of x and k

y=10×11

y= 110
