that would be 75 cause 45+30=75
why post if I'm supposed to ignore LOL
The value of x when y = 25 is 10.
Thus, the correct answer to the question is Option A. 10
From the question given above, we were told that y varies directly as x. This can be written as:
y ∝ x
Removing the proportionality sign, we have
<h3>y = Kx. </h3>
Next, we shall determine the constant K. This can be obtained as follow:
x = 4
y = 10
<h3>Constant (K) =? </h3>
y = Kx.
10 = K × 4
Divide both side by 4

Finally, we shall determine x when y is 25.

y = 25
<h3>x =?</h3>
y = Kx

Cross multiply
5x = 25 × 2
5x = 50
Divide both side by 5

<h3>x = 10</h3>
The value of x when y = 25 is 10.
Therefore, the correct answer to the question is Option A. 10
