Answer:
Step-by-step explanation:
-5/2 × (3x + 4) < 6x - 3x
-15/2x - 10 < 3x
-15x - 20 < 6x
-15x - 6x < 20
-21x < 20
<u>x</u><u> </u><u>></u><u> </u><u>-</u><u>2</u><u>0</u><u>/</u><u>2</u><u>1</u>
Inverse Property, I am pretty sure. Not sure though.
Arc tan ( 1/√3 ) = arc tan ( √3/3 ) = 30°
180° = π ( in radians )
30° = 180°/6 = π/6
X+x+20+2x=180
4x+20=180
4x=160
x=40
1.7 miles: subtract 1.5 from 3.2 which equals 1.7 (make sure to line up the decimals!)
