<u><em>The correct question is</em></u>
Mary has 15 coins with the total value of $1.75 if the coins are nickels and quarters how many of each kind are there
Let
x ----> the number of nickel coins
y ----> the number of quarter coins
Remember that


we know that
Mary has 15 coins
so
-----> equation A
The total value of the coins is $1.75
so
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool

Step-by-step explanation:
If AC is equal to 140 and B is the midpoint of the line, then that would mean the line would be split in half thus having measures BA and BC. Both of the measures would have half of the full length so that would mean that BA and BC equals 70 since 140/2= 70
