Lucia has 10 dimes and nickels worth a total of $0.60. use the graph to find the number of dimes and nickels that lucia has. pls i wanted to understand this but obviously i'm to stupid to understand this on my own pls

The system has one solution, so it is consistent independent. The graphs intersect at the point (2, 8), which can be checked algebraically. Complete a table of values for each line.

The point (2, 8) is the solution to the system of equations. Since (2, 8) is the solution to the system of equations, Lucia has 2 dimes and 8 nickels. 

hope it helps :) feel free to ask anymore questions 

The answer is 41.7 because 1.39 times 30 is 41.7
