Question

if x is directly proportional to y and x=25 and y=35.find the value of x if y=56​

Answer 1

Answer:

40

Step-by-step explanation:

if X is directly proportional to y ,

that means (X1/y1)=(x2/y2);

therefore,(25/35)=(x2/56)

x2=(5*56)/7;

x2=40.

Answer 2

Answer:

x = 40

Step-by-step explanation:

$\frac{x}{y} = \frac{25}{35} = \frac{5}{7}$

$7x = 5y$

$x = \frac{5y}{7}$

when y = 56

$x = \frac{5 \times 56}{7} = 5 \times 8 = 40$
