Given that y varies directly with y = 99 and x = 11. Find the value of y when x = 3?
Given that y varies directly with y = 99 and x = 11. Find the value of y when x = 3?
Explanation
Given y varies directly with x, so y = kx.
Given y = 99 and x = 11,
99 = k × 11
k = 9
Now, y = 9x
When x = 3,
y = 9 × 3
y = 27
