29 us. 2ft. 11 in. + 55 yd. 1 ft. 10 in. + 13 yd. 1 ft.3 in.

99 yd

Step-by-step explanation:

When I add these, I line them up vertically

  29 yd. 2ft. 11 in.

+ 55 yd. 1 ft. 10 in.

+ 13 yd. 1 ft.  3 in.

97 yd  4ft   24 in

We know that 12 in = 1 ft

so 24 in = 2ft

Subtract 24 in and add 2 ft

97 yd  4ft   24 in

           +2ft  -24 in

97  yd   6ft

We know 3 ft = 1yd

so 6ft = 2yd

Subtract 6ft and add 2 yd

97  yd   6ft

+2yd   - 6ft

99 yd

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
