Answer:
1. The two numbers are 4 and 8.
Step-by-step explanation:
1) variables: x and y
2) x + y = 12, y - x = 4
3) graph using desmos or another graphing calculator
4) the solution is x = 4, y = 8, or 4 and 8. This means that 4 and 8 can be added to equal 12, and the difference between them is 4.
Answer:
Each Angle of Decagon = 144 degrees
Step-by-step explanation:
The interior angles of a decagon add up to 1440
If they are of the same measure, then every angle will be equal to:
Each Angle of Decagon = 1440/10
Each Angle of Decagon = 144 degrees
So $25 - $17.35 = $7.65
7.65÷ 17 = 45
45 = 45 min
