The distance between Maritza's house and her school is 12.5 kilometers. The bus stop is 11.75 kilometers from school. How many meters must she walk to the bus stop?

She must walk 750 meters to bus stop.

Step-by-step explanation:

Given: Distance between Maritza's house and her school (A)= 12.5 kilometers.  (Total distance)

Distnance between Bustop and school (B)=  11.75 kilometers

Distance she need to walk to reach bus stop = A - B

=  12.5 - 11.75  kilometers

= 0.75 kilometers

= 0.75 x 1000 meters   [ 1 kilometer = 1000 meters]

= 750 meters

Hence, She must walk 750 meters to bus stop.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

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
