Answer:
x≤−8
Step-by-step explanation:
2x+3≤x−5
Step 1: Subtract x from both sides.
2x+3−x≤x−5−x
x+3≤−5
Step 2: Subtract 3 from both sides.
x+3−3≤−5−3
Answer is
x≤−8
Let's see
so you have to add the bottom numbers and the top numbers then add the whole numbers so it's 23 15\28
The answer to the first question is 30.
Arc tan ( 1/√3 ) = arc tan ( √3/3 ) = 30°
180° = π ( in radians )
30° = 180°/6 = π/6
