B
Step-by-step explanation:
6n - 2(4n + 7) + 4= -2 firstly you open the bracket
6n - 8n - 14 + 2 = -2 then you collect the like terms
6n - 8n= -2 + 14 - 4 then add and subtract and divide by the coefficient
-2n= 12 - 4
-2n = 8
= n = 8 ÷ -2
n = -4
48(5)=n
when n= the amount of time that Alisa practiced the piano.
Alisa practiced for 240 minutes.
48+240= t
