Arayanna is making a batch of brownies that feeds 4 people. How many batches of the recipe does she need to make to feed 37 people ?

so basically you divide 37 by four because there are 37 people and a pack of brownies makes 4

Step-by-step explanation:

s0 you would need 10 batches because if you make nine 9 times 4 is only 36 so there is 37 people who would like a brownie

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".

the infinity sign
