Best ResponseYou've already chosen the best response.0I've already got part A... A = 9(x+23)/2 2A = 9(x+23) 2A/9 = (x+23) 2A/9  23 = x x = 2A/9  23

Best ResponseYou've already chosen the best response.0ok so take the equation that is had from part a, and instead of the variable, substitute it 108 then solve, u get it now?

Best ResponseYou've already chosen the best response.0the equation is x=2a/923 so 2x108=216 216/9=24 2423=1 x=1

Best ResponseYou've already chosen the best response.0So is it this? 108 = 9/2(x+23) 108 = 9(x+23)/2 216 = 9(x+23) 216/9 = x + 23 24 = x+23 24  23 = x 1 = x x = 1

Best ResponseYou've already chosen the best response.0ok so we need to solve for n, this means we need to set an equation that solves for n so what we need to do is isolate the variable "n" so your steps are

Best ResponseYou've already chosen the best response.0–np – 90 > 30 first add 90 to both sides np>120 then you want to divide by p n>120/p then finally u have to divide by 1 since there is an invisible 1 next to the p and we need to get rid of that negative n>120/p is your final answer!

Best ResponseYou've already chosen the best response.0I was taught that if you divided by a negative, the sign was flipped. Am I confused about that?

Best ResponseYou've already chosen the best response.0yes whenever u divide anything my a negative it becomes the oposite sign, youre correc about that!

Best ResponseYou've already chosen the best response.0So should the sign be flipped at the end in this?
