Question

4. Simplify the following expressions.
a) -150 +[{(–24) – 50 ÷ (-10 + 16 × 2 - 17)} +120]​

Answer 1

Answer:

= -150 + [{(-24) - 50 ÷ (-10 + 32 - 17)} + 120]

= -150 + [{-24) - 50 ÷ ( -27 +32)} +120]

= -150 + [{-24 - 50 ÷ 5} + 120]

= -150 + [{ -24 - 50× 1/5 } + 120]

= -150 + [{ -24 - 10} +120]

= -150 + [ -34 +120 ]

= -150 + 86

= -64
