Answer: 10 percent
Step-by-step explanation:
because she was supposed to do 40 she did only 12 so it is 10%
Okay luv so let's solve this equation together:
8n-(2n-3)=12
simplify
8n+-1(2n-3)=12
8n+-1(2n)+(-1)(-3)=12
8n+-2n+3=12
(8n+-2n)+(3)=12 Combine like terms
6n+3=12
Then subtract from both sides
6n+3-3=12-3
6n=9
Then divide both sides by 6
6n/6=9/6
so...n=3/2
