Answer:
I help!!
Step-by-step explanation:
1. we know that Cara lost 4 less teeth than Kathleen, and the number of teeth Kathleen lost is represented by K. So, any equation that shows K-4=C will do.(feel free to use that equation)
2. this is essentially the same as the first equation, just reversed. So use + instead of -, and instead of ending up with =C you should end up with =K
You are still using the same plugs, C, 4 and K.
3. This is basic math. Cara lost 3 teeth, Kathleen lost 4 more than cara. So, 3+4=?
Answer:
the average velocity is 86 km/h for the trip
Step-by-step explanation:
from the definition of average velocity
average velocity = distance covered / time required = 1682 km /(19 h + 28 min/60 min/h) = 86 km/h
therefore the average velocity is 86 km/h for the trip

Answer:
(n-2)×180=1080
180n -360=1080
180n = 1080+360
180n =1440
dividing by 180
n=8
hence it is a regular polygon with 8 sides .I.e it is an octagon
Step-by-step explanation:
we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180
where n is the number of sides
