Answer:

get 1 … what? free? half-price? something else?

Let x= price of 1 item

Then 3x= price of 3 items

Buy 2 , get 1 free

Total cost =2x

Discount =3x−2x=x

Discount percentage =x/(3x)=0.333…=3313%

Buy 2 , get 1 half price

Total cost =2x+0.5x=2.5x

Discount =3x−2.5x=0.5x

Discount percentage =0.5x/(3x)=0.1666…=1623%

If L || m, solve for x (9x+2) 119
algol13

Answer:

13.4

Step-by-step explanation:

(9x+2) 119  to solve for x you need to isolate it so subtract 119 so the equation would look like this  (9x+2) = -119. Once you do that you are going to subtract 2 from both sides of the equation (9x)= -121. And now you divide by 9 and you have your answer x= 13.4.

Solving quadratic equations by factoring <br> m(m-3)=0
KatRina [158]
Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3
