Jordan wants to buy an Xbox for $400. He has already saved $85. He gets $10 an hour working at Target. Write an equation to show how many hours Jordan must work in order to have enough money for his new Xbox.

equation: 400 = 85 + 10x

400 = 85 + (10 x 31.5)

Step-by-step explanation:

i'm not sure if you wanted me to solve it, but i will :D if it has () around it that means circle it not parantheses

400 - 85 = 315

10 x (31) = 310

10 x (0.5) = 315

31 + 0.5 = 31.5

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".
