Awebsite recieved 9347 visits during the first month of its launch. the third month witnessed three times the number of visits than the second month. if the website received 13455 visits over the three month period, how many visits did it witness during the second month?

There were 1027 visits in the second month.

Step-by-step explanation:

A website received 9347 visits during the first month of its launch. +

Let the number of visits in the 2nd month be = x

The third month witnessed three times the number of visits than the second month that becomes 3x.

The website received 13455 visits over the three month period.

We can add up all to get;

=>

=>

=>

=>

Hence, there were 1027 visits in the second month.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
