Answer:
is it 7.7 i am not sure
Step-by-step explanation:
use cross products to solve
5* (n-9) = 8*n
distribute
5n-45 = 8n
subtract 5n from both sides
-45 = 3n
divide both sides by 3
-15 = n
Answer:
4
Step-by-step explanation:
[45-27]÷9·2
18÷9·2
2·2
12x^2-4x-5=0
12x^2+6x-10x-5=0
6x(2x+1)-5(2x+1)=0
(6x-5)(2x+1)
6x-5=0 , 2x+1=0
6x=5 , 2x=-1
x=5/6 , x=-1/2
