Lisa’s pet shop has 2 fish tanks. tank a contains smaller fish who are fed 1 gram of food each per day. tank b contains larger fish who are fed 2 grams of food each per day. if tank b contains 2/3 the number of fish that tank a contains, will lisa ever feed both tanks the same amount of food?

Step-by-step explanation:

Yes! Tank B is giving the fish more food but it has less food so it can catch up to the amount of Tank A!

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".

the answer should be a. snail
