Answer:5) c= 25.12 cm
6) c= 282.6 m
7) c= 13.188 mi
8) c= 6.28 cm
Step-by-step explanation:
C= 2 x pi x r
Circumference = 2 x 3.14 x radius ( radius is half the diameter of the circle)
8(m-3)=56
8m-24=56
8m = 80
m= 80 /8
m= 10
Answer:
24
Step-by-step explanation:
m-n=16
when n=8
m-8=16
or,m=16+8
or,m=24
Answer:
never
Step-by-step explanation:
5 degrees above zero is never a negative, it's positive
Answer:
-16.4, (commutative property)
Step-by-step explanation:
(add, because they are both negatives) -5.2+(-8.4)= -13.6
Then add the (-2.8): -13.6 + (-2.8) = -16.4
Thats your first equation!!!
do the same thing for the other one, and by the way it the same answer.
Its commutative prop because its just switching positions and its adding negatives.
