Step-by-step explanation:
I just know. besides, it would take too long to write the explanation. Hope this helps :)
Answer:
i have made it in above picture
hope it helps
n = d + 3
5n + 10d = 150 cents
Substitute to solve for "d":
5(d+3)+10d = 150
15d + 15 = 150
15d = 135
d = 9 dimes
n = d+3 = 9+3 = 12 nickels
So 12 nickels!!
Answer:
Infinite solutions
Step-by-step explanation:
1) First, you can solve this easily by elimination. Multiply the first equation by -2 in order to cancel out terms when adding to the second equation.
2) Then, add the new set of equations together. However, everything cancels out, bringing us to 0 = 0. This means that the lines the equations make must be the same. Thus, all real numbers must make this equation true, meaning that there are infinite solutions.
