Answer:

PLZ MARK ME BRAINLIEST.

Step-by-step explanation:

Number Of Students who go to School by Walk = 27

Number Of Students who go to School by Bus = 45

Ratio of Student who go to School by Walk : Bus = 27 : 45

=> Ratio of Student who go to School by Walk : Bus = 3 : 5

Hence Ratio of Student who walk to students who ride the Bus is 3 : 5 is correct - True Statement

Number Of Students who go to School by Bike = 21

Number Of Students who go to School by Walk = 27

Ratio Bike : Walk = 21 : 27

=> Bike : Walk = 7 : 9

Hence for Every 7 Students who Bike there are 9 students who walk

=> For Every 7 Students who Bike there are 8 students who walk is not Correct

What is the value of x?

Answers

Write and solve an equation of ratios, as follows:

4 5
---- = --------
2x 3x-5

Then 12x-20 = 10x, and 2x=20. Thus, x = 10.
