% of decrease would be 100 - (22*100)/28
=100-78.57 = 21.43%
Answer:
1) 14°
2)117°
3) 78°
4) 66°
5) 64°
6) 28°
7)35°
8) 48°
Step-by-step explanation:
just subtract both angles from 180 because all triangle's angles always add up to 180°
C. 56 + x =72 because the team player already scored 56 points you would need to add an unknown amount of points in this case x to find out how many points you need in order to reach 72 points and if you are curious how many points you need in order to get to 72 you need 16 points.
Answer:
x=9
y=12
Step-by-step explanation:
you know what the value of x is in terms of the second equation
so put that value into the first equation
so
-5(2y-15) + 4y = 3
-10y + 75 + 4y = 3
-6y + 75 = 3
-6y = -72
y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)
x = 2(12) - 15
x = 24 - 15
x = 9
