Question:

Use cross products to identify the equation needed to solve this proportion:

5/x = 2/9

0 5x = 18

0 2x = 45

O 9x = 10

O 2x = 14

Equation Given:

5/x = 2/9

Step by step explanation:

$: \implies \frac{5}{x} = \frac{2}{9}

$

equation formed

$: \implies \: 5 \times 9 = 2 \times x$

we have taken 9 up to multiply it with 5 and x up to multiply it with2

$: \implies \: 45 = 2x$

after multiplication we get 45 = 2x

extra steps:

$: \implies \: x=\frac{45}{2}$

transferring 2 to other side to divide it with 45

$: \implies \: x=22.5$

so finally we get 22.5
