Answer:
23
Step-by-step explanation:
1) (10*0.5)+(-6*-3)
2) (5)+(18) (The 18 isn't negative because of the rule that states "A negative and a negative will become positive"
3) 5+18=23
2* 10^4 would be bigger than 8* 10^3.
10^4 = 10000*2=20000
10^3 = 1000*8=8000
5n+ 5= 17
5n= 17-5
5n= 12
N= 12/5
N= 2.4
The answer is 2.4.
Hope this helps!
