Answer:

[tex]x=7[/tex]

Step-by-step explanation:

Formulate:

[tex]1\div50=x\div350[/tex]

Solve the equation:

[tex]\frac{1}{50}=\frac{x}{350}[/tex]

Swap the sides:

[tex]\frac{x}{350}=\frac{1}{50}[/tex]

Divide both sides of the equation by the coefficient of variable:

[tex]x=\frac{1}{50}\times350[/tex]

Cross out the common factor:

[tex]x=7[/tex]
The scale factor is 2, have fun :)
