A Fun Park refreshment stand sells only hotdogs and nachos. Hotdogs cost $2 and nachos cost $3. Marcus and his friends spent $34 at the refreshment stand. All together, they ordered a total of 14 items. How many hotdogs and how many nachos did they buy? Write a system of two linear equations in two variables that can be used to model the situation. Then choose a method to solve the system. Show your work and check your answer.​

true

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".
