5/8 voted for blue, 5/9 voted for green and 48 voted for red. how many voted for blue and how many voted for green?

let the total be x

blues = (5/8)x

greens = (5/9)x

but 5/8 + 5/9 = 85/72 which is > 1

not possible, so far we would have 85/72 of x

check the wording

Did it say: 5/9 of the remaining are green ?

Step-by-step explanation:

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".
