Answer 1

Answers:

a.) 134

b.) 0

c.) 200

d.) -2126

Step-by-step explanation:

a.) 120+[84÷7-{15-(25÷5+10+2)}]

120+[84÷7-{15-(5+10+2)}]

120+[84÷7-{15-17}]

120+[84÷7-{-2}]

120+[84÷7+2]

120+[12+2]

120+14

=134

b.) [180÷{12×10-15×9}] + 12

[180÷{120-135}]+12

[180÷{-15}]+12

[-12]+12

= 0

c.) -150+[25 of 10 -{(-50)+(-2 of 5) -40}]

-150+[25 of 10 -{-50+(-2×5)-40}]

-150+[25 of 10 -{-50-10-40}]

-150+[25 of 10 -{-100}]

-150+[25 of 10 +100]

-150+[25 × 10+100]

-150+[250+100]

-150+350

=200

d.) 650×(-2)+47-(-45)+{20 of (4-50)+2}

650×(-2)+47+45+{20 of (-46)+2}

-1300+92+{20×(-46)+2}

-1300+92+{-920+2}

-1300+92-918

-2218+92

= -2126
