Write an algebraic expression that can get you the final price of an item that originally cost $x with 10% off?

x - (x*0.1)

Step-by-step explanation:

A percentage is just a fraction/decimal. you'll get 10% of the number with the equation in parentheses, and we need to do that first. then we need to take the original price and subtract 10%

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
