Answer:

X=20! ^^

Step-by-step explanation:

Let's work out the value of x. We will use a skill called "cross multiplying".

[tex]\sf \cfrac{8}{x}=\cfrac{2}{5}[/tex]

We multiply 8 times 5 and obtain 40.

We multiply x times 2 and obtain 2x.

Our new equation is.

2x=40

We divide both sides by 2.

x=20
