Step-by-step explanation:
12z - 3 > 27z - 15
-15z - 3 > -15
-15z > -12
z < 12/15= 4/5
Answer:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x =
Then
∠ BOC = 2x = 2 × = ≈ 54.67° ( to 2 dec. places )
24. 9+(-6)=-3 is false because the 9 can’t go into the six and the six is by itself so it’s false
25. -10+(-10)=10 is false because you can’t add and multiply a positive number with a negative number, so it’s false
