Answer: 37</h3>
====================================================
Work Shown:
T = tens digit of the original number
U = units digit of the original number
U+T = 10 since the digits add to 10. Solve for U to get U = 10-T
10T+U = original number
10U+T = new number where digits are reversed
-----------
new number = (old number) + 36
10U+T = (10T+U)+36
10U+T = 10T+U+36
10(10-T)+T = 10T+10-T+36 ... plug in U = 10-T
100-10T+T = 10T+10-T+36
-9T+100 = 9T+46
100-46 = 9T+9T
54 = 18T
18T = 54
T = 54/18
T = 3 is the tens digit of the original number
U = 10-T
U = 10-3
U = 7 is the units digit of the original number
10T+U = 10*3+7 = 30+7 = 37 is the original number
73 is the reversed number.
73-37 = 36 is the difference, showing that 37 increased by 36 leads to 73. The answer is confirmed.

Step-by-step explanation:
sorry im still grade 3
Answer:
1. 4
2. 35
3. Her yard is a rectangle. She needs a 3000 feet of fence.
Step-by-step explanation:
1. The length of one side is 5 - 3 = 2 (subtract the y values)
The length of the other side is 7 - 3 = 4 (subtract the x values)
So the area is 2*4 = 8
2. The length of one side is 6 - 3 = 5 (subtract the x values)
The length of the other side is 7 - 0 = 7 (subtract the y values)
So the area is 5 * 7 = 35
3. The shape of her yard is a rectangle.
The length of one side of the fence is 5 - 0 = 5 units (subtract the x values)
The length of the other side of the fence is 10 - 0 = 10 units (subtract the y values)
The perimeter would be
(2*5) + (2*10)
= 30 units
Since the distance between each unit plotted is 100 feet, the total amount of fence needed would be
30 * 100
= 3000 ft
