The list is long, but here goes:
10/12, 15/18, 20/24, 25/30, 30/36, ... and so on.
Answer:
The numbers are in the wrong places in the diagram. 5.5m should be in the top bar diagram and 4.3 in the bottom. One equation could be 4.3 + d = 5.5.
Step-by-step explanation:
there are 6 1/6 per hour
multiply 1/3 by 6
1/3 * 6 = 6/3 = 2 miles per hour
Convert 6x - y = -4 into y = mx + b
Y - 4 = 6x
Y = 6x + 4
Substitute that into second equation
2x + 2(6x + 4) = 15
2x + 12x + 8 = 15
14x = 7
X = 1/2
6(1/2) - y = -4
3 - y = -4
-y = -7, y = 7
Final answer: x = 1/2, y = 7
