Answer:
x=-8
Step-by-step explanation:
3/4x+5-1/2x=3
3x+20-2x=12
x+20=12
x=12-20
x=-8
Cot=cos/son
Cot(a)=cos(a) / sin(a)
Cos(a)=5
Sin(a)=12
2sina-3cosa / 4sina-9cosa
2(12)-3(5) / 4(12)-9(5)
24-15 / 48-45
9/3
3
To the nearest 10: 26630
To the nearest 100: 26600
To the nearest 1000: 27000
If the number after the tens/hundreds/thousands unit is under five, you round down. If the number after is five or above, you round up.
Hope I helped, although the question is a bit ambiguous and there is no picture of a number line.
