Terryn has 25 one-dollar bills and wants to give an even amount to each of his two children. how many bills do each of terryn's children get, and how many dollars are left over? number of one-dollar bills each child gets: dollars left over:

Number of one-dollar bills each child gets: 12 dollars

Dollars left over: 1 dollar

Step-by-step explanation:

25/2=12.5

so round down to 12 cause 13(2) is 26 and you only have 25.

so 12(2)=24.

Each kid will get 12 dollars and there will be 1 dollar left over.

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".
