Answered by Ms. Sue
It's your turn now. You write the equation and we'll check it.
Answered by mikey
s= number sold 65-18=n 65-18 n=47
Answered by Ms. Sue
But there's no s in your equation. Does n = the number sold?

Other than that, your equation is correct.

Let's see your equation.

x=the lenght 2x+2(8)=ft 2x+16=8ft 2x+18-18-18=18-8 2x/2=10/2 x=10
Answered by Ms. Sue
x = number of slats

8 / 0.5 = x

or

96 / 6 = x
