Mitch and tom are playing a video game. mitch has eight less than triple the points that tom has. if mitch has 79 points how many points does tom have?

213

Step-by-step explanation:

mitch has eight less than triple the points do 79 - 8 = 71

so then you multiply by 3 and get 213

tom has 213 points

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".

p = 6s
