3X - 4 = 66 add 4 to each side 3X - 4 + 4 = 66 + 4 3X = 70 divide each sides integers by 3 (3/3)X = 70/3 X = 70/3 ------------------check in original equation 3(70/3) - 4 = 66 210/3 - 4 = 66 70 - 4 = 66 66 = 66 ---------------checks ( naturally, you could have canceled here, 3(70/3) and just got 70 )
The GCF is 2.
cot 70 + 4 cos 70 = cos 70 / sin 70 + 4 cos 70 = cos 70 (1/sin 70 + 4) = cos 70 (csc 70 + 4) Numerical answer varies, depending on whether 70 is in degrees, radians, or grads.

The LCM is 140.
The mean is (65 + 66 + 70 + 61)/4 = 262/4 = 65.5The mean is (65 + 66 + 70 + 61)/4 = 262/4 = 65.5The mean is (65 + 66 + 70 + 61)/4 = 262/4 = 65.5The mean is (65 + 66 + 70 + 61)/4 = 262/4 = 65.5
A quarter of 70 pounds is 17.5 pounds. To find a quarter of a number, you divide it by 4. In this case, 70 divided by 4 equals 17.5.
280/70 = 4
