Answer: ∠1 = 109°    ∠2 = 71°
<u>Step-by-step explanation:</u>
If the two angles form a linear pair, then their sum is 180°
   ∠1      +     ∠2     = 180°
(5x + 9) + (3x + 11) = 180
               8x + 20  = 180
               8x          = 160
                 x          = 20
∠1 = 5x + 9
     = 5(20) + 9
     = 100   + 9
     = 109
∠2 = 3x + 11
      = 3(20) + 11
      =    60  + 11
      =         71
   <u> CHECK:</u>
 ∠1   + ∠2 = 180°
109° + 71° = 180°
      180°   = 180°

Answer: 1 3/4
Step-by-step explanation: First, convert 4 1/2 and 2 3/4 to have like denominators.
4 1/2 = 4 2/4 because 1 x 2 = 2 and 2 x 2 = 4 = 2/4
2 3/4 stays the same.
Now, subtract 4 2/4 - 2 3/4             (4 x 4 = 16 + 2 = 18) and (2 x 4 = 8 + 3 = 11)
18/4 - 11/4 = 7/4 or 1 3/4
