Exerd At Kent Middle School, there are 104 students in the band and 84 students in the choir. What percent of the number of students in the choir is the number of students in the band?​

42

Step-by-step explanation:

104 in band

84 are in choir

so first what you need to do it add the students up- 104+84=188

now since there are 2 groups then you need to divide by 2= 188 divided 2=94

so it will be 94/2= 42 wholes.

answer: what equations are there

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".
