Basically 7(9b) is just multiplication so you get 63b times 78. You can't simplify it further cause you don't know what b is.
We are given the function
, and we are told to solve for
. Basically, we need to plug in
into all the variable spots in the given expression for
.
Therefore, the value of
when
is
. Hope this helps and have a phenomenal day!
You can see that each term is twice the previous one, with inverted sign.
You double a number by multiplying it by two, and you change its sign by multiplying it by -1.
So, you multiply each term by 2 and by -1, which results in a multiplication by -2.
Since we start with 3, the terms are
and so on. So, the general term is
15.5/1.25 = 12.4 pieces
We can't have .4 of a piece if they are all to be equal so we can obtain 12 pieces of ribbon in total.
