29) 50x + 4
Applying the distributive property,
(5*10x) + (5*4/5)
= 50x + (5*4/5)
= 50x + ((5*4)/5)
=50x + 20/5
=50x +4
30) 3x - 5/2
Applying the same logic as above,
(6*1/2x) - (6*5/12)
= (6/2x) - (30/12)
To simplify fractions, you must divide the numerator and the denominator by the same number that goes into both. We divided the numerator and the denominator by 6.
= 3x - (5/2)
= 3x - 5/2
= 3x - 2 1/2
32) 1 1/5x + 9/20
Applying the same logic as above,
(2/5 *3x) + (2/5*9/8)
= 6/5x + (18/40)
= 6/5x + 9/20
= 1 1/5x + 9/20
33) 2/15x - 4/9
Applying the same logic as above,
(2/3*1/5x) - (2/3*6/9)
= (2/15x) - (12/27)
= 2/15x - 4/9
