Answer:
x = 18, y = 45
Step-by-step explanation:
4x - 7 + a = 180 (linear pair)
But, a = 6x + 7 (alternate interior angles)
=> 4x - 7 + 6x + 7 = 180
=> 10x = 180
=> x = 18
Now, 3y - 20 = 6x + 7 (vertically opposite angles)
=> 3y - 20 = 6(18) + 7
=> 3y = 108 + 7 + 20
=> 3y = 135
=> y = 45
Hope it helps :)

Answer:
220
Step-by-step explanation:
110 cannot be the lcm for 20 but 10 and 110
so 220 can be the lcm for 20, 10, and 110
hope this helps
Answer:
x > 30
Step-by-step explanation:
divide both sides by 9
this gets the x on one side by itself.
270/9 = 30
don't let the inequality mess with you
treat it like an equal sign and leave it the way it is.
move things around it.
2³-4²
= 8-16
=-8
Hopefully this helps! Good luck! :)
