Answer:
-10
Step-by-step explanation:
you just subtract -4 by 6 and get -10
2 different things
if it is
xy=k or if it is x/y=k
direct or inverse variation
I will do the x/y=k one
9/-12=-3/4
x=-4
-3/4=-4/y
mutiply both sides by y
-3/4y=-4
mutiply both sides by -4/3 to clear fraction
y=16/3
Answer:
A = 72°
B = 108°
Step-by-step explanation:
5y - 3 = 3y + 27
5y - 3y = 27 + 3
2y = 30
y = 30/2
y = 15
A = 5y - 3
A = 5(15) - 3
A = 75 - 3
A = 72°
A + B = 180°
72° + B = 180°
B = 180° - 72°
B = 108°
