Answer:
2 2/3 lbs
Step-by-step explanation:
Convert Alya's mixed number to an improper fraction
3*1+1 = 4/3
multiply 4/3 times 2/1
4*2 = 8
3*1 = 3
8/3 - convert back to mixed number
8/3 = 2 2/3
A. f(-2)=3-6(-2)
-2f =3-(-12)
-2f=3+12
=15
divide both sides by 2
f=15/2
B. f(0)=3-6(0)
f=3
C.f(4)=3-6(4)
4f=3-24
f=21/4
