(264 in)/(5.5 in/piece) = (264/5.5) pieces = 48 pieces
_____
Division is the usual shortcut for repeated subtraction. You could subtract 5.5 from 264 until you get to zero. You would have to do 48 subtractions. It is easier to divide 264 by 5.5 to see how many times it goes.
Answer:
B 10x+5
Step-by-step explanation:
:)
For making mathematical induction, we need:
An
for which the relation holds true
if its true for
, then, is true for 
<h3>
base case</h3>
the relationship is not true for 1 or 2


but, is true for 3

<h3>
induction step</h3>
lets say that the relationship is true for n, this is

lets add 4 on each side, this is


now


if
then
, so



and this is what we were looking for!
So, for any natural equal or greater than 3, the relationship is true.
Answer is 1290.67. I rounded to the nearest tenth but it goes on.
