Our survey found that 56% of college students live on campus, 62% have a campus meal program, and 42% do both. In this example, what would be the denominator of the fraction if we wanted to find P(meal plan!live on campus)? A. 0.42
B. 0.62
C. 0.56
D. There is not enough information to answer this question

D.

Step-by-step explanation:

Nothings says what P is or represents so therefore the answer is D.

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".
