The value of y when x = 5 is 45
<h3><u>Solution:</u></h3>
Given that y varies directly with x. This can be written mathematically as:
y ∝ x
---- eqn 1
Where "k" is the constant of propotionality
Given y = 27 when x = 3. Substitute these values in eqn 1

<h3>k = 9</h3>
Substitute k = 9 in eqn 1
y = 9x ----- eqn 2
<u><em>To find: y = ? and x = 5</em></u>
Substitute x = 5 in eqn 2

Thus the value of y when x = 5 is 45

Answer:
2 and 1/4
Step-by-step explanation:
3.5 - 1.25 = 2.25
2.25 as a mixed number is 2 and 1/4
Answer:
146°
Step-by-step explanation:
The measure of the arc EF is equal to the angle subtended at the centre.
That is EF = 146°
(7, 9). the reason for this, is because on an x y coordinate plane, x first, then y second. east is positive, north is positive, therefore it is (7, 9)
