Walter wants computer software that cost $129. he has $57 saved. if he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take walter to save enough money to buy the software. 15x + 57 _> 129 (btw that’s an equal to symbol under it lol) a. x_> 4.8 b. x_< 4.8 c. x_> 12.4 d. x_< 12.4

In this question, it is given that

Walter wants computer software that cost $129. He has $57 saved.

he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

And we have to solve this inequality for x.

First we subtract 57 to both sides. And on doing so , we will get

Dividing both sides by 15.

Correct option is A.

10 glasses of juice could be made with 5 carrots, 1,500 orange juice, 2,000 papaya juice.

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".
