The answer is 3/10y^2 - 25y - 500. Glade I could help!
11. The two angles are vertical angles, which mean they are equal to each other.
14x - 5 = 13x
Add 5 to both sides:
14x = 13x + 5
Subtract 13x from both sides:
x = 5
12. The two angles are supplementary and when added together need to equal 180 degrees.
5x -20 + 3x = 180
Combine like terms:
8x -20 = 180
Add 20 to both sides:
8x = 200
Divide both sides by 8:
x = 200 /8
x = 25
2x+54= 3x
x=54
teh answer is 54
The answer will be (D)
Hope this helps
May i plz have brainliest?
