Answer:
y = 44
Step-by-step explanation:
Well if y varies directly with x it means that when y increases x increase and if y decrease x also decreases.
So let us put this in a equation,
y = kx
where 'k' is constant
so k = y/x
let us put the figures of x and y from given first statement;
x = 7 and y = 18
so, k = 18 / 7
which means, k = 2.57
lets put this value of k in the equation above,
we know from statement that, x = 17 and k = 2.57
so, y = 2.57 (17)
which means, y = 43.71
or we can round it off to, y = 44
