The table gives the numbers of teachers and students in grades 6 to 8 at earhart middle school.

grade teachers students

6 grade , teacher 1 , student 25

7 garde , teacher 2 , student 50

8 grade , teacher 3 , student 75

which teacher-to-student ratio maintains the proportional relationship described in the table?

teachers students

5 teachers, students 125

teachers students

4 teachers , students 120

teachers students

4teachers ,students 100

teachers students

6 teachers ,students 130

teachers students

7 teachers, students 125

im sorry if its like this i havent been having a good day

5 teachers, students 125

4 teachers, students 100

Step-by-step explanation:

step 1

Find  teacher-to-student ratio in the table

To determine the ratio, divide the number of teachers by the number of students

6 grade

7 grade

Simplify

8 grade

Simplify

step 2

Verify each case

case a) 5 teachers, students 125

Simplify

Divide by 5 both numerator and denominator

Compare  with the ratio described in the table

therefore

This ratio maintains the proportional relationship described in the table

case b) 4 teachers, students 120

Simplify

Divide by 4 both numerator and denominator

Compare  with the ratio described in the table

therefore

This ratio not maintains the proportional relationship described in the table

case c) 4 teachers, students 100

Simplify

Divide by 4 both numerator and denominator

Compare  with the ratio described in the table

therefore

This ratio maintains the proportional relationship described in the table

case d) 6 teachers, students 130

Simplify

Compare  with the ratio described in the table

therefore

This ratio not maintains the proportional relationship described in the table

case e) 7 teachers, students 125

Compare  with the ratio described in the table

therefore

This ratio not maintains the proportional relationship described in the table

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question
