Ihave 3 questions to ask :

1.list all of the integer values of x that are part of the solution set for the following inequality: −5≤x< −2 .

2.list all the positve integers that are in the solution set for 1≤x< 3 .
list all the negative integers that are in the solution set for −4≤y< −1 .

3.lyon bought some bracelets and an necklace for his younger sister. he bought 5 bracelets that each cost the same amount and a necklace that cost $3.50. lyon spent less
than $13 altogether.

which inequality can be used to find the cost of each bracelet?
a .5b+3.50> 13
b .5b−3.50> 13
c. 5b+3.50< 13
d. 5b−3.50< 13

what is the highest possible price of each bracelet?

i do not know this sorry : (

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".
