Answer:
7) a = 60; b = 100
8) c = 20
9) d = 45
Step-by-step explanation:
7)
a + 120 = 180
a = 60
b + 80 = 180
b = 100
8)
5c + 4c = 180
9c = 180
c = 20
9)
3d + d = 180
4d = 180
d = 45
I think it would have to be 5 and 6 because those two make up 11 when you add them. hope this helps
(g+b)*8
first add all of the people
and then multiply that by 8
A straight line on a coordinate plane always represents a function would be true.
