X + 3 = 10. X + 3 - 3 = 10 - 3 X = 7 Double check your solution. X + 3 = 10 7 + 3 = 10 10 = 10 So X + 3 = 10 when X = 7.
10 - (3)3 = 10 - 9 = 1 (10 - 3)3 = (7)3 = 343
3/10 = .3 = 30%or3/10 = (3 x 10)/(10 x 10) = 30/100 = 30%
3+1/3 = 10/3. The reciprocal of 10/3 is 3/10.
(10 + 10 + 10) / 10 = 30 / 10 = 3 / 1 = 3
