Answer 1

Answer:

32

Step-by-step explanation:

First solve small brackets (  )                  

Then solve curly brackets { }

Then big brackets or box brackets  [ ]

=19 + 1/5x [{(-20) + 55 } – (13-3)]

=19 + 1/5x [{(-20) + 55 } – 10]

=19 + 1/5x [{20 + 55 } – 10]   additive inverse of - 20 is +20

=19 + 1/5x [ 75 – 10]

=19 + 1/5 x 65

=19 +0.2 x 65

=19 + 13

=32
