in his bank account, zaire has $90 more than one-fifth the amount of money that eathan has in his account. zaire has $190 in his bank account. how much money does eathan have in his account?

it is a reproduction.

step-by-step explanation:

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".

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
