Answer:
Step-by-step explanation:
-3 + 1/2n = 1/2 (-n + 14)
distribute
-3 + 1/2n = -1/2n + 7
-1/2n
cancel out -1/2n
-3 = n + 7
-10 = n
subtract 7
n = -10
C is also the best answer
Answer:
83
Step-by-step explanation:
Let the number of robbers be x
If they share 6 rolls each, the tota rolls will be 6x and since they have five remainder, the overall total is then 6x+5
In case they share 7 rolls each, it means they have 7x rolls but here they will be less 8 rolls hence 7x-8 is the overall total.
Equating these two
7x-8=6x+5
Arranging similar terms
7x-6x=8+5
x=13
Therefore, the robbers are 13
The rolla they have will be
6(13)+5=83
Or
7(13)-8=83

positive, its above 0

Answer:
2
Step-by-step explanation:
7x4-3x8+2^2-6 : you have to do exponents 1st
7x4-3x8+4-6 : next you multiply 7x4 and -3×8
28-24+4-6 : you add -24+4
28-20-6 : you subtract 28-20
8-6 : you subtract 8-6
2 : thats your answer
