Answer:
1. -11
2. 3
3. 18
4. 30
Step-by-step explanation:
[tex]1. \: 2( - 5) + ( - 3)( - 7) \\ = ( - 10) + 21 \\ = 11[/tex]
2.
[tex]27 \div ( - 9) - (3)( -2 ) \\ = 27 \div ( - 9 ) + 6 \\ = - 3 + 6 \\ = 3[/tex]
[tex]3. \: \: 16 + (42 - 2 \times 3) - 34 \\ = 16 + (42 - 6) - 34 \\ = 16 + 36 - 34 \\ = 18[/tex]
[tex]4. \: \: 42 \div 7 \times (39 \div 3 - 8) \\ \\ = 42 \div 7 \times (13 - 8) \\ = 42 \div 7 \times (5) \\ = 6 \times 5 \\ = 30[/tex]
