Let me know the answer! i will give branliest

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

5050

hope this !
