2.50 x 4 = 10
20 - 10 = 10
so his change would be $10
Answer:
Step-by-step explanation:
The angles that you have shown are called same side exterior angles.
All same side exterior angles add to 180 degrees
Since we know this, we can make the following equation:
2y+2+4y-2=180
6y=180
y=30
To get each angle you can plug in y:
2*30+2=62
4*30-2=118
I hope this helps :)
Answer:
Step-by-step explanation:
2y + 7 - 4y = 15 - 2y - 8
-2y + 7 = 7 - 2y
-3n - 2 = 4n - 2 - 7n
-3n - 2 = -3n - 2
