Answer:
The answer would be 14 becuase they are adding 6 to every other number.
Step-by-step explanation:
Because a triangle is 180 degrees, and you already have a right angle that leaves 90 degrees for the rest of the angles.
So, (2x) + (x+15) = 90
Combine like terms.
3x + 15 = 90
Subtract 15 from 90.
3x = 75
Divide.
75/3, so x = 25.
When you decrease 20 to 11,the decrease is 9
the percentage decrease is
(9/20)*100
=9*100/20
=9*5
=45%
Answer:
1+2=3

Answer:
y = 12
Step-by-step explanation:
To solve this equation... The function is basically:
y = 3x - 15
So by substituting in x=9:
y = 27 - 15 = 12.
y = 12
Hope this helps.
