Answer:
40
Step-by-step explanation:
Angle 1 and 2 are alternate angles
Then they are equal
2x+20=3x+10
Solve for x
X=10
Then 2 (10)+20 =40
2. Addition POE(property of equality)
3. Add variables
4. Subtraction of integers
5. Division of integer
Answer:
They're both proportional because everything's moving at a constant rate. Think of it this way: If a car travels for 50 miles per hour and the speed never changes, it's proportional. If that car at hour 1 traveled at 50mph and then at hour 2 traveled at 60mph, it would be nonproportional since the speed is increasing and changing.
