Ineed the answer to the blank questions

We have that
n 12 part a)
actual distance> 124 miles
map distance> 4 cms
scale factor of the map =124 miles/4 cms=31 miles/cm

n 12 part b) 
map distance=21 cms
actual distance?
[actual distance]=[map distance]*factor scale> 21*(31)=651 miles

n 13) 
we know that
(13.5/9)=(x/8)> x=(13.5/9)*8> x=12 units

n14)
we have that
x/26=(32-x)/18> 18x=832-26x> x=18.91 units

All points to the left of zero on a horizontal number line are negative. a number line is a picture of a graduated straight line that serves as abstraction for real numbers. this number line can be extended to the left to represent numbers which are smaller than 0. such numbers are called negative numbersmark me brainliest

The answer is option c.
