John batted 9 times for an average of 32. what was his total?

288

Step-by-step explanation:

From a data set, the average would be the "central" value of that set. It has the formula:

Where

Sum means the sum of all the numbers

Number means the Number of Numbers there are in total

Here, It is given:

Average = 32

Number = 9

So we substitute and find the "sum" to be:

The total (sum) is 288

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".
