(12x40)+(18x6)
or
(12x40)+(18x6)=588
thank you for letting me answer and god bless <3
Let h be the price of the helmet (not hemelt). Then 0.05h= $1.50.
To determine the price of the helmet, divide both sides of this equation by 0.05:
h = $30
The helmet is $30 before sales tax is applied, and $31.50 with tax.
Answer: 1, -1
Step-by-step explanation: This is a difference of squares when factored,
(x+1)(x-1)
Let's check using FOIL(First, outside, inside, last)
x * x =x^2
1 *x =x
x * (-1) =-x
1* -1 =-1
so x^2 +x -x -1
=x^2 -1
