Answer:
arc BC = 84 degrees
Step-by-step explanation:
notice:
need to find n before finding arc BC
(13n -16) + (7n + 12) + 6n = 360
13n + 7n + 6n - 16 + 12 = 360
26n - 4 = 360
26n = 364
n = 364/26 = 14
so arc BC = 6*14 = 84 degrees
Answer:
The correct unit price would be $1.23.
The contractor divided 103.32 by 7, resulting in an error.
Step-by-step explanation:

To find the error of the contractor, let's try substituting in a number (7) provided in the question to see if we get $14.76 per pair:

Divide.

Y-4=5(x-6)
y-4=5x-30
5x-y=26
5x+(-1)y=26
