Answer:
12
Step-by-step explanation:
let the number be a
30-3a= -6
collect the like terms
30+6=3a
3a=36
a=12
The number is 12
To prove the divisibility lets expand each number first to get the complete picture of the problem
51^7 = 8.974106779 . 10^11
51^6 = 1.75962878 . 10^10
(51^7 - 51^6) = 8.974106779 . 10^11 - 1.75962878 . 10^10
= 8.798143901. 10^11

= 3.51925756. 10^10
That is the answer expressed in scientific notation
= 35192575600
Which means the divisibility is proven

Answer:
oof its been like 7 months and no one never answered
Step-by-step explanation:
so sad ;-;
This would be a question that would involve division.
We do: (1,600 ÷ 4) and therefore, this would give us

just as we were looking for, and therefore,
B would be your correct answer.
