4) A large group of students and adults went on a trip to the zoo. Four busses were completely filled and 3 adults drove to the zoo. If a total of 171 people went on
the trip, write and solve an equation to determine how many people were on
each bus

36 is the final answer! : )

you should pay $0.88

what is the image?

2? if not the correct answer you might need to provide more information

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".
