Step-by-step explanation:
5) = 0 (-17 + 20 = 3,... 3 + -3 = 0)
6) = -34 (-34 + 25 = -9,... -9 + -25 = -34)
9) = -4 (7 + -11 = -4)
Chow,...!
Ok so the first one is
1.x=135
2.x=-23
3.x=3
4.x=70
You have two totals: total # of bills and total amount of $. Using x as #of 20s, and y as # of 50s, you can use the system
x+y=18
20x+50y=450
Root: (-4/3, 0)
vertical intercept: (0, -4)
Answer:
