Now, solve the equation for x

Divide both sides by 0.20

Hence, the bill before for the lunch before the tip was $13.75

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

you can't solve x because it is 2 linear equation and you only have one equation
