Answer:

John is 9.21 km form the school.

Step-by-step explanation:

John leaves school to go home. His bus drives 6 kilometres north and then goes 7 kilometres west. It is required to find John's distance from the school. It is equal to the shortest path covered or its displacement. So,

d=\sqrt{6^2+7^2} \\\\d=9.21\ km

So, John is 9.21 km form the school.

1. 4b - 2 : the product of 4 and a number (b) decreased by 2

2. the sum of 15 and 4 times a number......15 + 4x

3. 8 fewer boys then girls...how many boys.......b = g - 8

4. It will be less then 1 because of the negative exponent....a negative exponent will mean the number is less then 1...I dont really know how else to explain it.

5. Doug is twice Anna's age...doug is 34 years old
   I dont know the 5 step plan...but I am putting what I do know

   d = doug's age
   a = anna's age
   
   d = 2a
   d = 34
   
   34 = 2a
   34/2 = a
   17 = a....so anna is 17

   check..
   d = 2a
   d = 2(17)
    d = 34 (correct)

Unfortunately, there are no given choices. However, I could provide the possible inequalities from the given problem. Converting the given to inequalities: 3.2x + 0.8y < 50 x + y = maximum There is no other limiting equation (i.e. the total cost of the books) such that the, if you wanted to maximize x, results to minimum y and vice versa.
