Answer 1

Answer:56 students

Step-by-step explanation:

So look 6th grade total 42 and 8th is 72 and the total is 170 but he want 7th grade total so what I did is 42+72=114

Then I did 170-114=56 so the total of 7th grade is 56.

Answer 2

The value of the variables x, y, and z will be 45, 24, and 56.

What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

The students at spring field school can join either the orchestra or the marching band.

Let the missing value x, y, and z are given in the table.

The table is given below.

                           Orchestra         Band           Total

6th Grade                24                  18                 42

7th Grade                32                   x                   y

8th Grade                 z                   27                 72

Total                        101                 69                 170

Then the value of x, y, and z are calculated below.

For value of z, the equation will be

72 = z + 27

 z = 72 – 27

 z = 45

For value of x, the equation will be

18 + x + 27 = 69

      x + 45 = 69

              x = 69 – 45

              x = 24

For value of y, the equation will be

y = 32 + 24

y = 56

Then the value of the variables x, y, and z will be 45, 24, and 56.
