You want to buy a pet iguana you already have 12 and plan to save 9 per week

i cant see the full question

Step-by-step explanation:

to answer it you take the total cost of the pet and subtract the amount you already have that = the remaining balance needed to pay off the pet. divide that remaining balance by the 9.00 a week you will continue to save and that answer is the number of weeks it will take.

total pet cost - amount have saved = remaining balance

remaining balance / 9 (amount to save each wee)

= number of weeks needed to pay off pet

if you have a decimal for an answer you will need to add one week to the total to allow for the full payoff

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".
