The freezer contains vanilla and chocolate ice cream. Chocolate ice cream contains 12 servings less than vanilla. How many servings of vanilla ice cream are in the freezer if there are a total of 40 servings of ice cream? (Solve by building an equation)

26 servings

Step-by-step explanation:

Let the number of servings of vanilla ice cream be x.

Number of servings of chocolate ice cream

= x -12

(since it has 12 servings less than vanilla)

Total servings= servings of chocolate+ vanilla

x + x-12= 40

2x -12 =40 (simplify)

2x= 40 +12 (+12 on both sides)

2x= 52 (simplify)

x= 52 ÷2

x= 26

Therefore, there are 26 servings of vanilla ice cream in the freezer.

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".

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
