2 metric tons is 4,409.2 pounds.
cos(3t) = cos(2t + t) = cos(2t)*cos(t) - sin(2t)*sin(t) = [cos2(t) - sin2(t)]*cos(t) - 2*cos(t)*sin(t)*sin(t) = [cos2(t) - sin2(t)]*cos(t) - 2*cos(t)*sin2(t) then, since sin2(t) = 1 - cos2(t) = [2*cos2(t) - 1]*cos(t) - 2*cos(t)*[1 - cos2(t)] = 2*cos3(t) - cos(t) - 2*cos(t) + 2*cos3(t) = 4*cos3(t) - 3*cos(t)
2000 pounds is equal to 1 ton in the United States customary system. This is the standard conversion, where 1 ton is defined as 2000 pounds. In other measurement systems, such as the metric system, a ton can refer to different values, but specifically for the US ton, the equivalence holds true.
To compare 18,000 pounds and 9 tons, it's important to convert tons to pounds. One ton is equivalent to 2,000 pounds, so 9 tons is equal to 18,000 pounds (9 x 2,000 = 18,000). Therefore, 18,000 lb and 9 t are equal.

2t and 1000lb
4000
Yes; because 2t is 4000 lb.
To convert from tons (t) to pounds (lb), you need to multiply by 2,000. Therefore, 2 tons is equal to 4,000 pounds.
3r + 3r + 2t = 6r + 2t
2t-3-3 = 7 2t = 7+6 2t = 13 t = 6.5
Probably simplest (easiest not to get mixed up) to convert both to lb, subtract, then convert back to tons. 1 ton = 2000 lb, so: 6t 300 lb = 6x2000 lb + 300 lb = 12000 lb + 300 lb = 12300 lb 2t 900 lb = 2x2000 lb + 900 lb = 4000 lb + 900 lb = 4900 lb 12300 lb - 4900 lb = 7400 lb convert back to tons: 7400 lb/ 2000 lb per ton = 3 tons 1400 lb
19-2t = 7 -2t = 7-19 -2t = -12 t = 6
2t-5t=-3t
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
4t +7
75+2t=100-2t 4t=25 t=6.25 So t is 6.25 or 25/4.
