Answer 2

Answer:

$8y = 20x$

Step-by-step explanation:

Given

$y=\dfrac{5}{2}x$

Required

Determine equivalent expressions

A. 5y = 2x

$y=\dfrac{5}{2}x$

Multiply through by 5

$5 * y=\dfrac{5}{2}x * 5$

$5y=\dfrac{25}{2}x$

This is not equivalent

B.  8y = 20x

$y=\dfrac{5}{2}x$

Multiply both sides by 8

$8 *y=\dfrac{5}{2}x * 8$

$8y=\dfrac{5 * 8}{2}x$

$8y=\dfrac{40}{2}x$

$8y = 20x$

The other options are not clear.

However, another possible relationship is when

$y=\dfrac{5}{2}x$is cross multiplied

This gives:

$2y = 5x$
