Answer:
D)
Step-by-step explanation:
A is incorrect because: 2(6) -3(-4)<9 which is 24<9 which is not true
B is incorrect because: 2(-1) -3(-9)<9 which is 25<9 which is not true
C is incorrect because: 2(2) -3(-5)<9 which is 19<9 which is not true
D is correct because: 2(-3) -3(-3)<9 which is 3<9 which is true
For number 7:
a) The sum of the adjacent angles is 180. Because if its any three angles thats half of the angles all together 3/6 = 180/360.
b) The sum of the angles in the center is 360 degrees. Because 60 x 6 = 360.
c) The unknown angles (center angles) are 61.25 degrees.
For number 8 (bonus):
It's C) 90 Degrees, because it's a right angle.
Hope this helps :)
No, you do not have enough
Answer:
7
Step-by-step explanation:
Work with PEMDAS
(Subtracting a negative from a negative is the same thing as adding)
7-(-19)-18+(-19)+18
7-(-19)=26
-18+(-19)=-37
26-37+18= 7
