To getyour answer, just divided 3.24 by 12. You will get 0.27. So the answer is each pencil costs 27 cents or 0.27.
Odd numbers are represented as 2n+1 where 2 is a natural number ( negative and possitive whole numbers)
consecutive odd numbers are 2 away from each other so 3 consecutive odd numbers would be
(2n+1),(2n+1+2),(2n+1+2+2)
the all add to -15 so they must all be negative
2n+1+2n+1+2+2n+1+2+2=-15
add like terms
6n+9=-15
subtract 9 from both sides
6n=-24
divide both sides by 6
n=-4
subsitute
first number=2n+1=2(-4)+1=-8+1=-7
second number=2n+1+2=2(-4)+3=-8+3=-5
third number=2n+1+2+2=-8+5=-3
the numbers are -7,-5, -3
the answe ris B
The answer should be this;
11.5(7) + 10.7 (8)= 166.1
