Answer:
C) 8
Step-by-step explanation:
-5(a+3)=-55
a+3=-55/-5
a+3=11
a=11-3
a=8
It is A. We have a ratio of
900 workers : 3.2×10⁵
Dividing by 9×10² becomes
1 worker :

×10³
3.2/9 is just 0.36 rounded so it is
1 worker : 0.36×10³
or A
Answer:

m < 1 = 80 degrees
Answer:
18x-3
Step-by-step explanation:
f(x)= 3x + 10x
g(x)=5x - 3
f(x)+g(x) = 3x + 10x + 5x - 3
Combine like terms
= 18x -3
