Answer:
c
Step-by-step explanation:
gm=cm+rg
gm-cm=rg
m(g-c)/g-c = rg/g-c
m=r g/g-c
-3m=4m-15
-3m-4m=-15
-7m=-15
-15/-7m
= -2.14
-15/-3-4= 2.14
51-3=48 slice.
48 slice/ 4 pizza= 12 slice
each extra large pizza have 12 slice.
the AnSwEr is
12 because 8x - 1=3x+4 the variable x represents the same value and x= 0
