Emily is making a punch that contains 75% apple juice and the rest ginger ale. the punch has 2 liters of ginger ale. part a: write an equation using one variable that can be used to find the total number of liters of apple juice and ginger ale in the punch. define the variable used in the equation and solve the equation. hint: 0.75x represents the number of liters of apple juice in the punch. (5 points) part b: how many liters of apple juice are present in the punch? show your work. (5 points)

7x7=4 so if u carry the 9 it will be 33

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".
