What is 327.24 rounded to the nearest whole number

327.24 rounded to the whole number (7) would be 327

The reason you would add up is if .2 was .5 or higher or any number you have to round up. If the number behind the number you need to round is 4 or less than you don't round it would be the same but if it is 5 or above you round up.

Hope it helps!

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".
