3840

Step-by-step explanation:

if 120 divided by 750 is 16% then 16% of 24000 is 3840

Number of students out of surveyed students who live within 500 miles

= Total number of students surveyed - Number of students who live 500 miles away or more

= 750 - 120

= 630

Ratio of number of students surveyed to the number of students out of them living within 500 miles

= 750:630

= 25:21

Let the actual number of students living within 500 miles be x.

If the students are surveyed randomly then,

Ratio of number of students surveyed to the number of students out of them living within 500 miles = Ratio of actual number of students to the number of actual students living within 500 miles

=> 25:21 = 24000:x

=> 25/21 = 24000/x

=> x = (24000×21)/25

=> x = 504000/25

=> x = 20160

So, the number of actual students who live within 500 miles is 20160.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
