Answer:
-4x-1
Step-by-step explanation:
combine 4x and -8x to make -4x and combine -2 and 1 to make -1
42 x 61 = 2562
2562/215 = 11.92
12 total bags are needed

f(x) = 1 / x
f(1/2) = 1 / (1/2)
Reciprocal of 1/2 is 2, since you flip numerator and denominator:
f(1/2) = 2
2w+5w-6+4w
=10w+4w-6
=14w-6
=2(7w-3)
