If y varies directly as x, and y is 18 when x is 5, which expression can be used to find the value of y when xis 11 à - 18 (11)

y-1 (11)

y-(19)(5)

y-1315

Step-by-step explanation:

y varies directly as x

It means y=kx

y=18 when x=5

y=kx

18=k5

k=18/5

y=? When x=11

y=ky

Substitute the value of k

y=18/5(11)

=18×11/5

=198/5

=39.5
