5=z−4−3
5=z-7
move -7 to the other side
sign changes from -7 to +7
5+7=z-7+7
5+7=z
Answer: z=12

Answer:
The length of the arc is 7.536cm
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 6cm
π = 3.14
c = 2π * r
we replace with the known values
c = 2 * 3.14 * 6cm
c = 37.68cm
The length of the circumference is 37.68cm
Now we calculate the fraction that corresponds to this arc with the rest of the circumference
(2 pi /5) / (2pi) = 1/5
now we multiply the circumference by the fraction
37.68cm * 1/5 = 7.536cm
The length of the arc is 7.536cm
